Abstract
The infrared and Raman spectra of tetramethylurea (TMU, $((CH_{3}){2}N){2}CO)$ and hexamethylphosphoramide $(HMPA, ((CH_{3}){2}N){3}PO)$ have been obtained. The pyrimidal configuration about the nitrogens and the deviation from $C_{2v}$ point group symmetry as reflected in the spectra of TMU will be discussed. Preliminary vibrational assignments for HMPA will be presented.
