Structure and dynamics of cyclic amides: The rotational spectrum of 1,3-dimethyl-2-imidazolidinone
The structure and the internal dynamics of the lactam 1,3-dimethyl-2-imidazolidinone, also known as N, N’-dimethylethyleneurea, have been investigated through the analysis of its free jet absorption rotational spectrum. One conformer has been assigned. The pure mu(b)-type spectrum, recorded in the 59.6-74.4 GHz frequency range entails an inertial defect Delta(c) = -16.39 u angstrom(2), indicating that the molecule has C-2 symmetry with a twisted arrangement of the ring. The methyl internal rotation barrier V-3 = 7.181 (3) kJ mol(-1) and the N-14 diagonal nuclear quadrupole coupling constants x(aa)= 2.14 (14) and (X-bb-X-cc) = 7.26 (6) MHz were determined from the analysis of the hyperfine structure. They are in good agreement with the ab initio MP2/6-311++G(d,p) calculations which also estimate the electric dipole moment value as 3.9 D. (C) 2017 Elsevier Inc. All rights reserved.
