✦ Synopsis
In a preliminary small-scale simulation, a high-energy, infrared frequency, left circularly polarized laser field has been used to induce rotational motion in liquid water at 293 K. The effect on the molecular dynamics has been analyzed subsequently using a range of molecular autocorrelation and cross correlation functions. The field symmetry is such as to make possible the existence in the laboratory and moving frames of reference of new cross correlation functions. The simulation shows laboratory-frame birefringence in the orientational and rotational velocity autocorrelation functions. The appearance of birefringence is coincident with that of cross correlations in the laboratory frame, and could be used experimentally for their determination, with computer simulation as an interpretative method.
