摘要：

The results of molecular beam Fourier transform microwave (FTMW) investigations of the van der Waals complexes of dimethyl ether with 1,1-difluoroethene/trifluoroethene are reported. The rotational parameters of the complexes have been interpreted in terms of a CS geometry with the two methyl groups lying out of the sigma(v) symmetry plane of complexes. The complexes are bound with three hydrogen bonds of which one is the stronger O... H-C type and two are the weaker F... H-C types. Some additional information on the structure and the hydrogen bond has been obtained from ab initio calculations. (C) 2003 Elsevier Science (USA). All rights reserved.
