THE EFFECT OF HINDERED INTERNAL ROTATION ON THE 3 MICRON SPECTRUM OF $CH_{2}SH$.

Author Institution: Department of Physics, Texas Technological CollegeTwo fundamental vibrations of $CH_{2}SH$ have been observed under high resolution $(0.06 cm^{-1})$ on a 3-meter Ebert-Fastie vacuum spectrograph: $\nu_{1}$, the $CH_{3}$ symmetric stretching mode at $2947.76 cm^{-1}$, and $\nu_{2}$, the essentially degenerate $CH_{3}$ asymmetric stretching mode at $3009.88 cm^{-1}$
