Collision-broadened halfwidths of three lines in the ν3 fundamental band and of four lines in the ν6 fundamental band of 12CH3D have been measured at temperatures between 123 and 295 K using the Doppler-limited spectral resolution of a tunable diode laser spectrometer. Temperature dependence of the linewidths has been determined in self-broadening and in broadening by H2, He, and N2.
