adiabatic transition-state theory

A form of transition-state theory in which the system is assumed to preserve its internal quantum states as it moves over the potential-energy surface. A detailed state-to-state scattering theory version of adiabatic transition-state theory has been referred to as the adiabaticchannel model.
