abstract

  • The i.r. and Raman spectra of carbonylbis(l-aziridine), (CH2CH2N)2C0, and N,N,N',N'-tetramethylurea have been recorded. A complete assignment of the fundamental vibrational frequencies of carbonylbis(l-aziridine) has been made and a partial normal coordinate analysis was carried out to substantiate the assignment for the skeletal vibrations. Considerable mixing of several of the low frequency modes was found from the calculated potential energy distribution. The C2v symmetry assumed for the molecule was compatible with the observed spectra. The barrier to internal rotation about the C(O)-N bonds was calculated to be approximately 9 kcal mole based on the observed far-infrared frequency near 100 cm-1. The spectra of N,N,N',N'-tetramethylurea were recorded and a partial normal coordinate calculation was carried out to aid in the assignments for the skeletal vibrations of carbonylbis(1-aziridine). 1972.
