We have measured broadening and shift coefficients for ro-vibrational lines of the nu_ {2} and 3nu_ {2} bands of CH3D, with the most abundant gases in planetary atmospheres (i.e. H2 and He for the giant planets and in the case of Titan, N2) as the foreign buffer gases, using a multispectral fitting technique developed by the Reims group. The spectra of the nu_ {2} band, near 5 microns, were recorded under high resolution and two temperatures (295 and 197K) using a FTS at the G.S.M.A. Reims laboratory. Those of the 3nu_ {2} band, near 1.6 microns, were recorded also under high resolution but only at room temperature with the FTS at Kitt Peak National Observatory. Broadening and shift coefficients were determined for lines of nu_ {2} up to J=20 in the P-branch and up to J=19 in the R-branch. For 3nu_ {2}, measurements were made up to J=14 in the P-branch and up to J=12 in the R-branch. In addition, for nu_ {2}, the temperature dependences of many of these coefficients were derived. Comparisons of the room temperature coefficients for the two bands show strong similarities in both their magnitudes and dependences with J and K. These similarities suggest that the temperature dependence determined for nu_ {2} can be used for 3nu_ {2}.
