Atomic Spectra And Radiative Transitions by I.I. Sobelman


Original Title: Atomic Spectra And Radiative Transitions

My previous book on the theory of atomic spectra was published in Russian about fifteen years ago. Besides the traditional problems usually included in a book on atomic spectroscopy, some other problems arising in various applications of spectroscopic methods were also discussed in the book. These include, for example, continuous spectrum radiation, excitation of atoms, and spectral line broadening. Extensive revisions were made in the English version of the book published by the Pergamon Press in 1972, especially in the chapter devoted to the problem of excitation of atoms. This book is intended as the first part of a two-volume presentation of the theory of atomic spectra, atomic radiative transitions, excitation of atoms, and spectral line broadening. The aim in preparing these new books has been to stress the problems connected with the most interesting applications of atomic spectroscopy to plasma diagnostics, astrophysics, laser physics, and other fields, which have been developed very intensively in recent years. The content of this first volume, devoted to the systematics of atomic spectra and radiative transitions, is similar to that of Chapters 1-6, 8 and 9 of the old book, but considerable revision has been made. Some sections, such as those on the Hartree-Fock method, the Dirac equation, and relativistic corrections, have been deleted. At the same time, more attention is paid to radiative transitions. More extensive tables of oscillator strengths, prob abilities, and effective cross sections of radiative transitions in discrete and continuous spectra are given.

Spectra by Anne Knish


Original Title: Spectra

Excerpt from Spectra: A Book of Poetic Experiments It may be noted that to Spectra, to these re flected experiences of life, as we perceive them, adheres often a tinge of humor. Occidental art, in contrast to art in the Orient, has until lately been afraid of the flash of humor in its serious works. But a growing acquaintance with Chinese painting is surely liberating in our poets and painters a happy sense of the disproportion of man to his assumed place in the universe, a sense of the tortuous grotesque vanity of the individual. By this weapon, man helps defend his intuition of the Absolute and of his own obscure but real relation to it.

George R R Martin S A Game Of Thrones 5 Book Boxed Set Song Of Ice And Fire Series by George R. R. Martin


Original Title: George R R Martin S A Game Of Thrones 5 Book Boxed Set Song Of Ice And Fire Series

For the first time, all five novels in the epic fantasy series that inspired HBO’s Game of Thrones are together in one eBook bundle. An immersive entertainment experience unlike any other, A Song of Ice and Fire has earned George R. R. Martin—dubbed “the American Tolkien” by Time magazine—international acclaim and millions of loyal readers. Now this bundle collects the entire monumental cycle in the most convenient format available: A GAME OF THRONES A CLASH OF KINGS A STORM OF SWORDS A FEAST FOR CROWS A DANCE WITH DRAGONS “One of the best series in the history of fantasy.”—Los Angeles Times Winter is coming. Such is the stern motto of House Stark, the northernmost of the fiefdoms that owe allegiance to King Robert Baratheon in far-off King’s Landing. There Eddard Stark of Winterfell rules in Robert’s name. There his family dwells in peace and comfort: his proud wife, Catelyn; his sons Robb, Brandon, and Rickon; his daughters Sansa and Arya; and his bastard son, Jon Snow. Far to the north, behind the towering Wall, lie savage Wildings and worse—unnatural things relegated to myth during the centuries-long summer, but proving all too real and all too deadly in the turning of the season. Yet a more immediate threat lurks to the south, where Jon Arryn, the Hand of the King, has died under mysterious circumstances. Now Robert is riding north to Winterfell, bringing his queen, the lovely but cold Cersei, his son, the cruel, vainglorious Prince Joffrey, and the queen’s brothers Jaime and Tyrion of the powerful and wealthy House Lannister—the first a swordsman without equal, the second a dwarf whose stunted stature belies a brilliant mind. All are heading for Winterfell and a fateful encounter that will change the course of kingdoms. Meanwhile, across the Narrow Sea, Prince Viserys, heir of the fallen House Targaryen, which once ruled all of Westeros, schemes to reclaim the throne with an army of barbarian Dothraki—whose loyalty he will purchase in the only coin left to him: his beautiful yet innocent sister, Daenerys. “Long live George Martin . . . a literary dervish, enthralled by complicated characters and vivid language, and bursting with the wild vision of the very best tale tellers.”—The New York Times

Infrared Absorption Spectra 1959 by Herbert Hershenson


Original Title: Infrared Absorption Spectra 1959

Infrared Absorption Spectra: Index for 1945 -1957 contains 16,000 references to published infrared absorption spectra in 33 American and European journals and book. This index aims to provide a means for the location of published absorption spectra from 1945 to 1957, compiling references that consist of an abbreviated symbol of the journal, volume number, and page where an actual spectrum of the compound is reproduced. This book is arranged according to the compounds whose spectra are given, which is roughly similar to that used in Chemical Abstracts. This text is suitable for chemistry students and professionals conducting work on infrared absorption spectra.

Molecular Spectra And Molecular Structure by Gerhard Herzberg


Original Title: Molecular Spectra And Molecular Structure

TEXT BOOK MOLECULAR SPECTRA and MOLECULAR STRUCTURE I. SPECTRA OF DIATOMIC MOLECULES by GERHARD HERZBERG. Originally published in 1939. PREFACE: Eleven years ago I published a volume entitled Molecular Spectra and Molecular Structure I. Diatomic Molecules which was followed in 1945 by a second volume Infrared and Raman Spectra of Polyatomic Molecules. The first volume has been out of print for a number of years but the demand for it seemed to justify a new edition. Although the book has been completely revised and brought up to date, its general plan has remained substantially unchanged. Concerning this plan it seems therefore appropriate to quote from the preface of the first edition I have endeavored to give a presentation which is readable by the beginner in the field and also will be useful to those who do or want to do research work in this field. In order to assist the former, I have frequently made use of small type for those sections that are not necessary for an understanding of the fundamentals. For the benefit of those working in the field, numerous references to original papers have been included. A satisfactory presentation of molecular spectra and molecular structure is nowadays not possible without treating thoroughly, apart from the empirical results, the theoretical background also. Therefore I have included as much of the theory of molecular spectra as is possible without going into the more difficult mathematical details. A large number of diagrams, graphical repre sentations of eigenfunctions and potential curves, as well as energy level dia grams, serve to illustrate and to explain the theory. On the other hand, I have added numerous carefully selected spectrograms of bands and band systems some of which have been taken specially for this purpose in order to give an accurate idea of tho experimental material that forms the basis of the developments. While of course most of the material presented is not new, it seems that the actual procedure followed in analyzing a band spectrum has not previously been given as specifically in a book of this kind. The same holds for the ap plications of band spectra to other parts of physics, to chemistry, and to astro physics given in the last chapter. I hope that both these features will be found useful. In the eleven years since the publication of the first edition the subject Spectra of Diatomic Molecules has developed vigorously even though not as rapidly as in the preceding two decades. Most of the progress made has been consolidation and slow evolution rather than revolution. Exceptions to this statement are the amazing advances made by applying the new tools of molecular beams and microwaves to diatomic molecular problems. Naturally I have incorporated these advances of recent years in the present new edition...

Recent Results In The Theory Of Graph Spectra by D.M. Cvetkovic


Original Title: Recent Results In The Theory Of Graph Spectra

The purpose of this volume is to review the results in spectral graph theory which have appeared since 1978. The problem of characterizing graphs with least eigenvalue -2 was one of the original problems of spectral graph theory. The techniques used in the investigation of this problem have continued to be useful in other contexts including forbidden subgraph techniques as well as geometric methods involving root systems. In the meantime, the particular problem giving rise to these methods has been solved almost completely. This is indicated in Chapter 1. The study of various combinatorial objects (including distance regular and distance transitive graphs, association schemes, and block designs) have made use of eigenvalue techniques, usually as a method to show the nonexistence of objects with certain parameters. The basic method is to construct a graph which contains the structure of the combinatorial object and then to use the properties of the eigenvalues of the graph. Methods of this type are given in Chapter 2. Several topics have been included in Chapter 3, including the relationships between the spectrum and automorphism group of a graph, the graph isomorphism and the graph reconstruction problem, spectra of random graphs, and the Shannon capacity problem. Some graph polynomials related to the characteristic polynomial are described in Chapter 4. These include the matching, distance, and permanental polynomials. Applications of the theory of graph spectra to Chemistry and other branches of science are described from a mathematical viewpoint in Chapter 5. The last chapter is devoted to the extension of the theory of graph spectra to infinite graphs.

Hertha Sponer A Woman S Life As A Physicist In The 20th Century So You Won T Forget Me by Marie-Ann Maushart


Original Title: Hertha Sponer A Woman S Life As A Physicist In The 20th Century So You Won T Forget Me

Just three women qualified for a professorship in physics in Germany before the Second World War. All three began their careers with great promise; all three had to leave Hitlers Germany, among them Hertha Sponer. An ambitious girl, she had to struggle to achieve the education she craved, culminating in a Ph.D. at the University of Gttingen. There followed an apprenticeship in Berlin, and work under the aegis of James Franck, around the time he received the Nobel Prize. Their academic world was shattered by the Nazis. Sponer reluctantly embarked on a new life in North Carolina. She succeeded as Professor of Physics at Duke University. She became a recognized authority on the electronic spectra of aromatic molecules (benzene and derivatives). Late in life, she became the second wife of James Franck.

Infrared Spectra Of Mineral Species by Nikita V. Chukanov


Original Title: Infrared Spectra Of Mineral Species

Over the last 30 years, Dr. Nikita V. Chukanov has collected IR spectra of about 2000 mineral species, including 247 holotype samples. In this book, he presents 3309 spectra of these minerals with detailed description and analytical data for reference samples. In the course of this work, about 150 new mineral species have been discovered. After an introductory chapter, infrared spectra of minerals are given together with the descriptions of standard samples used (occurrence, appearance, associated minerals, empirical formula etc.) and some comments. Sections are organized according to different classes of compounds (silicates, phosphates, arsenates, oxides etc.).
