Microwave Spectrum and Dipole Moment of Dimethylnitrosamine

Abstract

Abstract The microwave spectrum of the (CH3)2NNO and (CH3)2 15N15NO species have been studied and the rotational constants evaluated. By comparison of the inertia defects of the two species it can be stated that the nuclear frame of the molecule is planar, which is in agreement with the reported electron diffraction results. The dipole moment of the (CH3)2 15 N15NO species has been determined. Further studies on the internal rotation of the two methyl tops are in progress together with the analysis of the spectra of other isotopically substitued species.
