Nonadiabatic Processes in Molecular Collisions

  • John C. Tully
Part of the Modern Theoretical Chemistry book series (MTC, volume 2)


Substantial effort has been directed toward developing methods for describing molecular collision processes that are electronically adiabatic, i.e., for which it can be assumed that nuclear motion evolves on a single potential energy hypersurface. A number of recent reviews are devoted to this subject.(1–8) Considerably less attention has been paid to processes that are nonadiabatic,i.e., that involve electronic transitions between potential energy surfaces. This is in spite of the fact that nonadiabatic behavior is both common and important, even in thermal energy collisions.
