Analysis of the torsional Raman spectrum of a pyramidal molecule, dimethylamine

Chemical Physics, 1993
Abstract Overtone Raman spectra of dimethylamine (DMA) are analyzed yielding accurate torsional potential parameters. Neglecting the inversion motion of the amino-hydrogen in DMA the group G 18 is the proper molecular symmetry group to analyze the measured torsional Raman spectrum.
