Abstract:Qausiclassical trajectories QCT have been used to investigate energy transfer of various excited H X(X=O,S) stretching and H X H bending normal modes in H 2O and H 2S, respectively. Average energy in each normal mode as a function of time is obtained. The results demonstrate that only those modes with frequencies close to or with the same vibrational symmetry as that of the excited mode participate in the energy transfer.
Keywords:Normal mode  Local mode  Energy transfer  QCT method  Hessian matrix
