Rotational State Dependence of the Predissociation Dynamics in H2O, D2O (C̃1B1 and β1A1)

Abstract

The two photon photodissociation of H2O, D2O (C̃1B1) from individually selected J'Ka'Kc' rotational levels in the (000) vibrational level has been investigated experimentally using a line-narrowed, tunable KrF laser. The results establish a strong dependence on the magnitude of 〈Ja'2〉1/2 ≅ Ka', both for the heterogeneous predissociation path and for the subsequent branching on the β1'A1 potential at the Renner-Teller intersection with Ã1B1 near linearity.
