Two-color sub-Doppler circular dichroism: A four-vector correlation molecular-dynamics experiment

Abstract

In molecular collisionand reaction dynamics the precision of data obtainable from an experiment is determined by the extent the vectors of linear and angular momentum are specified. The highest degree of specification comes from four-vector correlation, two before and two after the collision. Here we introduce the new technique of two-color sub-Doppler circular dichroism and demonstrate the first four-vector correlation molecular-dynamics experiment. Results are given for elastic and inelastic collisional processes between ${\mathrm{Li}}_{2}$ and the rare gases Ar and Xe.
