Proceedings of SPIE Vol. 11916 : 27th International Symposium on Atmospheric and Ocean Optics, Atmospheric Physics, 2021, Moscow, Russian Federation. P. 1191607-1-1191607-5Abstract: The work is aimed at measuring the depolarization ratio of the ν1 Raman band of methane in nitrogen and carbon dioxide media at a pressure of 50 atm. To improve the accuracy of estimating the ν1 intensity in the depolarized spectrum, we used the simulation of the ν3 band. It was found that the environment of nitrogen and carbon dioxide has a negligible effect on the depolarization ratio of the ν1 Raman band of methane.
