Abstract

The study presents a method for fast modeling of the ν₂ Raman band of methane at any pressure of the medium and spectral resolution of the spectrometer. For this purpose, the spectra of methane with a resolution of ~ 0.4 cm^-1 in the range of 1240- 1850 cm^-1 at a pressure of 1-20 atm were recorded and fitted by Voigt profiles. It was shown that the error of this method using the obtained parameters did not exceed 5% at a pressure more than 5 atm. The demonstrated algorithm can be used in fast data acquisition methods for methane-bearing media by Raman spectroscopy applications.
