Notes:
The Raman and infrared spectra of N,N-diethylformamide, N,N-diethylacetamide, N,N-diethylchloroacetamide and N,N-diethylpropionamide were measured. Raman polarization measurements were also made. A normal coordinate analysis was carried out for N,N-diethylformamide, N,N-diethylacetamide and N,N-diethylchloroacetamide using a 63-parameter modified valence force field. The force constants were refined in an overlay least-squares technique using vibrational frequencies of the molecules to obtain a converged set of meaningful force constants. The reliability of the force constants so obtained was tested by making a zero-order calculation for N,N-diethylpropionamide. The potential energy distributions and eigenvectors calculated in the process were used to make unambiguous vibrational assignments.
