Cooperative Phenomena in Jahn—Teller Crystals

This book by Kaplan and Vekhter brings together the molecular world of the chemist with the condensed matter world of the physicist. Prior to the collapse of the Soviet Union, chemists in the West devoted lit­ to relationships between molecular electronic structure and tle attention solid-state vibr...
