Abstract

We report in this work the Ne- and Kr-broadening coefficients of C H for 36 lines in the P, Q and R branches of the ν fundamental band. These rovibrational lines with J values ranging from 3 to 23 are located in the spectral range 919-1024 cm. The measurements were carried out at room temperature with a tunable diode-laser spectrometer. The collisional line widths obtained by fitting Rautian profiles to the measured lineshapes are slightly larger than those derived from Voigt profiles. The C H line-broadening by Kr is more important than the broadening by Ne.
