Description
Summary:In this work we present new experimental and theoretical values for the line broadening coefficients of the Q-branch Raman lines of autoperturbed N2. For the experimental determination of the coefficients, high resolution stimulated Raman loss spectra of the Q-branch of N2 at different pressures were obtained at 77, 194 and 298 K. Simultaneously, we carried out Close-Coupling calculations at 77, 113, 194 K, and Coupled-states calculations at 298 K rendering a set of theoretical line broadening coefficients that could be directly compared to those obtained from our measurements and from available data in the literature. We observe a good agreement between theoretical and experimental values.
