Abstract
The symmetry principles governing the nonlinear interaction of intense laser radiation with molecular ensembles show that dynamical interaction phenomena exist in the ensemble even though the induced frequency-dependent polarization could be purely imaginary and unobservable in the static limit. An example is computer simulated in the S enantiomer of bromochlorofluoromethane, showing clear effects on the orientational and rotational velocity correlation functions and by Fourier transforming these functions, the dielectric and far-infrared spectra. Conditions are suggested for its experimental observation and orders of magnitude calculated for the appropriate mediating tensors.
