Abstract :
[en] The initial wave packets and H2O+ and D2O+ in their B 2B2 /2A' states are expanded in the frozen gaussian basis set proposed by Heller. The gaussian functions are propagated on the adiabatic and diabatic potential energy surfaces resulting from the conical intersection with the A 2A1/2A' states. Autocorrelation functions are calculated separately for the adiabatic and the diabatic motions of the nuclei. These autocorrelation functions are compared with their experimental counterparts. The agreement is qualitatively good and the isotope effects are well accounted for.
