Trajectory binning scheme and non-active treatment of zero-point energy leakage in quasi-classical dynamics

Abstract

By expressing an unknown state in terms of a complete set, a simple scheme for approximate quantization of the continuous vibrational-rotational energy distributions that are obtained from quasi-classical trajectory calculations is suggested. The problem of zero-point energy leakage is also revisited, and the new method tested on the prototype O + OH and H + D2 reactions.
