dc.description.abstractThe $J\; 0 \rightarrow 1$ and $1 \rightarrow 2$ a-type transitions of methyl isocyanate $(CH_{3}NCO)$ have been observed. The spectrum is moderately complicated by internal rotation. Four lines in the 0-1 region and nineteen lines in the 1-2 region are easily observable at dry-ice temperature. The spectrum of the molecule have been calculated for range of CNC bond angles from $120^{\circ}$ to $140^{\circ}$ and a range of barriers from 0 to 1200 cal/mole. The best qualitative agreement with the observed spectrum corresponds to a CNC bond angle of approximately $140^{\circ}$ and a surprisingly low barrier to internal rotation for the methyl group of about 20 cal./mole. Efforts to improve this qualitative agreement have to far been unsuccessful.en_US
