Graduate-level text and research reference presenting a complete guide to the theory of modern atomic spectroscopy.
'... a worthwhile addition to a university library ...' Andrew M. Ellis, Chemistry in Britain 'The writing of Theoretical Atomic Spectroscopy is an admirable achievement ... The book is indispensible to anyone working in atomic theory and should be of interest also to those working in applied spectroscopy.' Mats Larsson, Journal of Analytical Atomic Spectrometry '... a complete ... guide to the theory of modern spectroscopy of atoms ... The book contains a large number of new results, which have been mainly published in Russian and are therefore almost unknown to western scientists. A graduate-level text and research reference, this book is aimed primarily at atomic physicists, astronomers and physical chemists, but will also be of value to physicists, astronomers and chemists in other areas who use spectroscopy in their work.' K. Moskalev, Optik
