Abstract
We report in this work the Ne- and Kr-broadening coefficients of C2H4 for 36 lines in the P,Q and R branches of the ν7 fundamental band. These rovibrational lines with J values ranging from 3 to 23 are located in the spectral range 919-1024 cmâ1. 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 C2H4 line-broadening by Kr is more important than the broadening by Ne.
