Absorption of monodeuteromethane 12CH3D at 4.5 μM, analysis of the overtone band 2ν6

Abstract The overtone band 2 ν 6 of 12 CH 3 D is analyzed in the range 2088–2433 cm −1 . The parallel and perpendicular components, centered at 2316.266 and 2323.297 cm −1 , are strongly interacting, giving rise to a number of “forbidden” transitions and large A 1 A 2 splittings. Six hundred twelve transitions including J ′ values up to 13 are assigned; the vibration-rotation constants for the upper state v 6 = 2 are derived from these data, allowing the reproduction of the experimental wavenumbers with a rms equal to 0.007 cm −1 . Some intensity measurements are used to estimate the overall band strength of 2 ν 6 .
