Term: adiabatic transition-state theory
https://doi.org/10.1351/goldbook.A00146

Definition:
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 (reaction) surface. A detailed state-to-state scattering theory version of adiabatic transition-state theory has been referred to as the adiabatic channel model.
