NEW POSSIBILITIES OF OVERLAPPING RAMAN BAND RESOLUTION BY METHODS OF CARS SPECTROSCOPY

New possibilities for the resolution of Raman bands, provided by polar ization-sensitive CARS in combination with a Phase-mismatching techniq ue, are presented. The use of this combination of techniques allows on e to achieve the most informative spectra and resolve the complex stru cture of inhomogeneously broadened contours. The variation of the reso nant/non-resonant ratio using a phase-mismatching technique and the sp ecial possibilities of polarization CARS spectroscopy in lineshape for mation are used. The results of an investigation of a cyclohexane and naphthalene mixture and of n-pentane by polarization CARS in combinati on with a phase-mismatching technique are presented.
