[The vibration-rotational analysis of the high resolution ir spectrum of the CH3D molecule].
High-resolution Fourier transform spectra of the band of the CH3D molecule near 6428cm(-1) have been recorded on a BRUKER IFS 120HR Fourier-transform spectrometer with multipass cell with a length of 20m, an unapodized resolution of 0.004cm(-1) was achieved. Vibration-rotation analysis in Local-mode can provide accurate enough initial values to predict the band origins. The vibration-rotation transitions of CH3D molecule were assigned by using the ground state combination differences and least-squares fitted to yield ten vibration-rotation constants for the band of CH3D molecule near 6428cm(-1). Vibration assignment in Normal-mode and Local-mode expressed that the band of CH3D molecule near 6428cm(-1) is 3V2 vibration states of CH3D molecule.
