We have measured the vibrational Raman spectrum of a 1.2-mm-thick polystyrene film by using this film as an optical waveguide in a waveguide-stimulated Raman gain experiment. A gain factor of 1.3% was measured for the strong benzene mode at 1002 cm21. This value is in reasonable agreement with theoretical predictions.
