Abstract
The infrared and Raman spectra of $NH_{2}CN$ and $ND_{2}CN$ have been examined in the liquid state. Polarization data imply a planar configuration and seven fundamentals can be assigned as the planar vibrations of a molecule having $C_{2v}$ symmetry. For wavelengths longer than $15\mu$, however, the spectra are too rich to be consistent with the planar configuration. The low frequency bands are best interpreted on the basis of a non-planar equilibrium configuration with a small barrier to inversion about the amino-nitrogen $atom.^{1}$ This small departure from planarity produces such a small effect on the ''planar'' fundamentals that the polarization data are indistinguishable from those expected from a truly planar molecule.
