NONADIABATIC TRANSITIONS IN THE PHOTODISSOCIATION OF HCL

Nonadiabatic dynamics accompanying the photodissociation of HCl via excitation X 1Σ+→A 1Π have been investigated. The energy-dependent branching ratio 2P 1/2/2P3/2 of the Cl fragment resulting from the "exact" numerical solution of the time-dependent nuclear Schrödinger equation is compared to the branching ratio gained from a classical-path ansatz. Different sets of potential energy functions taken from previous investigations are used. It is shown that discrepancies between the results of two recent papers are due to substantial differences concerning the nonadiabatic transition moments between the corresponding potential functions. © 1994 American Institute of Physics.
