Abstract:Absorption spectra of hot methane were recorded in the 2300-3200 cm$^{-1}$ spectral region ($\nu_{3}$ mode) using a Bruker 120/125 HR Fourier transform spectrometer. Methane was heated in a quartz cell in a tube furnace at 295, 473, 673, 873 and 1073 K. Line broadening of the methane spectra was investigated by adding 50, 150 and 400 Torr of H$_{2}$ as a broadening gas to 0.5 Torr of methane. A preliminary spectral fit of the methane data was performed using Voigt line shape functions with the WSpectra program. The temperature and pressure dependence of the line broadening parameters were studied; additional spectra are needed for more temperatures and pressures. A more sophisticated analysis using non-Voigt line shapes and a multi-spectral fit will be carried out.
