Lasers are playing a more and more dominant role in modern optical spec- troscopy, offering an increased potential for high resolution and, thus, for more detailed spectroscopic information on dynamic and structural param- eters. This book on Zero-Phonon Lines and Spectral Hole Burning in Spec- troscopy and Photochemistry gives a concise and very useful survey of some of the pioneering and current work on solid state spectroscopy of various groups in the USSR. It focusses on the optical Mossbauer analogue, the "zero-phonon line" , and "hole burning" spectroscopy, a method which increases the...
