High-frequency wings of rototranslational Raman spectra of gaseous nitrogen

The depolarized, rototranslational light-scattering spectrum of gaseous nitrogen at 295 K has been computed in the far spectral wings, taking into account both the allowed Raman lines and collision induction spectra. Good agreement between our theoretical results and the experimental data [Y. Le Duff and V. Teboul, Phys. Lett. A 157, 44 (1991)] has been observed. Our findings indicate that most of the intensity at large frequency shifts is due to the wings of the pressure broadened Raman lines. {} 1996 The American Physical Society.
