✦ Synopsis
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 \mathrm{GHz}). T2t has an intermediate energy with respect to those of two conformers ( (T 1) and (T 2 g) ) 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 (\mathrm{MW}) investigation because of the very small value of the (\mu_{a}) dipole moment component. c) 1995 Academic Press. Ins
