The microwave spectrum of a third conformer (T2t) of N-methyl ethylenediamine has been assigned using a free-jet millimeter-wave spectrometer in the frequency range 60-78 GHz. T2t has an intermediate energy with respect to those of two conformers (T1 and T2g) previously assigned with conventional microwave spectroscopy [W. Caminati, A. C. Fantoni, and B. Velino, J. Mol. Struct. 157, 385-398 (1987)]. The assignment of the T2t conformer was missed in the previous MW investigation because of the very small value of the mu(a) dipole moment component.

1995
Abstract
The microwave spectrum of a third conformer (T2t) of N-methyl ethylenediamine has been assigned using a free-jet millimeter-wave spectrometer in the frequency range 60-78 GHz. T2t has an intermediate energy with respect to those of two conformers (T1 and T2g) previously assigned with conventional microwave spectroscopy [W. Caminati, A. C. Fantoni, and B. Velino, J. Mol. Struct. 157, 385-398 (1987)]. The assignment of the T2t conformer was missed in the previous MW investigation because of the very small value of the mu(a) dipole moment component.File in questo prodotto:
