摘要：

Microwave spectra of chloromethylmethylether and its 21 isotopically substituted species were measured. The rs structure of this molecule was determined from the observed moments of inertia under several assumptions which were necessary to avoid the use of unreliable rs coordinate values. Structural parameters obtained for this molecule are roughly close to those reported by Ikeda et al. [J. Mol. Spectrosc. 53, 101 (1974)]. However, one of three CH bond lengths for the methyl group exhibits a remarkably high value (1.130 Å). From the structure obtained, the barrier to internal rotation of the methyl group was calculated taking into account the coupling effect with the skeletal torsion. © 1979.
