Scientific paper

High-resolution spectra of the ν_4 fundamental band of 13CH_4 broadened by N_2 at temperatures relevant to the atmosphere of Titan were recorded using temperature-controlled absorption cells installed in the sample compartment of a Bruker IFS-125HR Fourier Transform spectrometer (FTS) at the Jet Propulsion Laboratory (JPL). Analysis of these spectra using multispectrum fitting has determined half widths, pressure-induced shifts, line mixing parameters and their temperature dependences for transitions belonging to a number of P- and R-branch J-manifolds. The analysis examined in detail the temperature-dependence of N_2-broadened half width and pressure-induced shift coefficients over the entire temperature range from 80 K to 296 K. The results are compared with other published measurements of N_2- and air-broadened methane parameters.
