Recently the anti-Stokes spectroscopy after strong vibrational excitation via resonant absorption was rediscovered, for the study of population relaxation dynamics. A closer theoretical inspection of this experimental approach reveals that properly chosen polarization conditions allow the study of molecular reorientational motion. Furthermore the sign of a/γ (the invariants of the Raman polarizability tensor) can be determined. Experimental data for chlorinated alkanes will be presented. © 1996 American Institute of Physics.
