✦ Synopsis

We repclrt near-Doppler-limited Raman spectra of the VI fundamentaI in methane using direct cw stknulated Raman gain spectroscopy enhanced by a muhipass optical cell. 25 -MHz resolution makes possiile a correct analysis of the fine structure of the vr band of methane_ We present line assigmnents to J = 10 and spectroscopic constants for this band which differ sigrdfiamly from pr&ous analyses.

We demonstrate the use of cw stimulated Brillouin gam (SBG) spectroscopy to measure high resolution Brillouin spectra of liquids. Results are reported for thirteen liquids at room temperature, all obtained in a polarized (VV) configuration with a scattering angle of 178'. The observed Brillouin freq
