N2 - He-broadening coefficients are measured for 28 lines of 12CH3F in the RQO (Ki = 0, ΔK = 1, ΔJ = 0) and RQ6 (Ki = 6, ΔK = 1, ΔJ = 0) branches of the v6 band, using a tunable diode laser spectrometer. The collisional widths obtained by fitting Rautian profiles to the measured shapes of the lines are slightly larger than those derived from Voigt profiles. The broadening coefficients for the lines belonging to the same low J transitions are significantly greater in the RQ0 branch than in the RQ6 branch. Moreover, they decrease on the whole with increasing J in the RQ0 branch and tend to increase from J varying from 7 to 10 in the RQ6 branch.
