Abstract
The infrared spectra of $CH_{3}SnH_{2}, CH_{3}SnD_{3}$, and $CD_{3}SnH_{3}$ have been obtained in the region $4000-250 cm^{-1}$. Coriolis constants for $CH_{3}SnH_{2}$ and $CD_{3}SnH_{3}$ were obtained from analyses of their vibration-rotation spectra. Fundamental and combination bands have been assigned and the assignments were confirmed using the Product Rule. The inactive torsional vibration ($A_{2}$ species) was calculated from the barrier to internal rotation and confirmed by assignments of combination bands. The normal coordinate analysis was performed using the Hybrid Orbital Force Field. The potential energy distributions show that except for the $CH_{3}$ rocking mode, the $CH_{3}$ vibrations can be regarded as ``group vibrations''. Coriolis constants were calculated and compared with the observed values.
