The inter-relation of rotational and translational motion in molecular dynamics.

Abstract

Abstract A review of the recent source literature on the statistical correlation between rotation and translation in condensed molecular matter rveals the extent to which computer simulation now provides fundamental new insights in this branch of molecular physics. Cross correlation functions of this type have been discovered in the frame of the molecular principal moments of inertia and direct in the lab. frame in the presence of a parity breaking external electric field. The non-inertial linear velocities and accelerations exist in both frames for a simultaneously rotating and translating molecule, and are shown to lead to major new insights into statistical cross correlation on the single molecule level. The relation between molecular dynamics and hydrodynamics is discussed in terms of these new correlations.
