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 vibronic phenomena. Treating quantum
mechanical problems wherein the adiabatic Born-Oppenheimer
approximation fails was done by "brute force. " With bigger and
better computers available in the West, molecular orbital
calculations were done on observed and conceived static structures
with little concern for any cooperativity of vibrational behavior
that might connect these states. While it had long been understood
in the West that situations do occur in which different static
structures are found for molecules that have identical or nearly
identical electronic structures, little attention had been paid to
understanding the vibrational states that could connect such
structures. It was easier to calculate the electronic structure
observed with several possible distortions than to focus on ways to
couple electronic and vibrational behavior. In the former Soviet
Union, computational power was not as acces sible as in the West.
Much greater attention, therefore, was devoted to conserving
computational time by considering fundamental ways to han dle the
vibrational connectivity between degenerate or nearly degenerate
electronic states.
