Using a diode-laser spectrometer, self-broadening coefficients have been measured at three temperatures (246.2, 226.2 and 150.2 K) for 11 spectral lines in the ν fundamental band of CH. The collisional widths have been obtained by fitting each experimental absorption profile with a Rautian model. The temperature dependence exponent n was also determined for each line, and found to be constant within experimental uncertainties. The mean value is equal to n = 0.676.
