Absorption spectra of methane in the 11000–11400 cm–1 spectral region were recorded with an IFS-125M Fourier spectrometer at pressures from 11 to 100 mbar, a room temperature, and a spectral resolution of 0.03 cm–1. A multipass cell 60 cm long with 44 passes provided a total path length of 2640 cm and threshold sensitivity to absorption of about 10–8 cm–1. Line centers, intensities, self-broadening, and selfshift coefficients of methane lines were determined by fitting Voigt profile parameters.
