MICROWAVE SPECTRUM OF METHOXYACETONITRILE

Author Institution: Department of Chemistry, Queen's UniversityA study has been made of the rotational spectrum of methoxyacetonitrile, $CH_{3}OCH_{2}CN$, in the 8 to 40 GHz region. R-branch a-type transitions of the gauche and trans conformers have been assigned yielding the rotational and centrifugal distortion constants (in MHz) [FIGURE] Strong vibrational satellites probably due to methyl torsion and torsion about the $O-CH_{2}$ bond are present in the spectrum of each conformer
