Abstract
The jet-cooled Fourier-transform microwave spectrum of N, N-dimethylacetamide was recorded in the region of 12–24 GHz, and was analyzed to determine rotational constants and nuclear quadrupole coupling constants. Coriolis-like coupling parameters characterizing interaction between internal rotation of methyl groups and the overall rotation were also determined from internal-rotation tunneling splittings of the rotational transitions. The Coriolis-like coupling parameters permitted determination of the barrier heights to internal rotation of the three methyl groups, which were found to be 677, 237, and 183 cm −1 for the C-methyl top, the trans- N-methyl top and the cis- N-methyl top, respectively.
