چکیده انگلیسی
The rotational spectra of dimethylether-d6-Ar and dimethylether-13C-Ar have been investigated by molecular beam Fourier transform microwave spectroscopy. The obtained rotational constants, when compared to those of the normal species, give contrasting indications on the conformation of the complex. We believe the indications given by the dimethylether-Ar/dimethylether-13C-Ar pair to be the correct ones. They suggest the Ar atom to lie in the Ïν symmetry plane of dimethylether perpendicular to the C-O-C plane, shifted towards the oxygen atom. This conformation is in agreement with several kinds of theoretical calculations. Probably isotopic substitution effects make the data from dimethylether-d6-Ar not directly compatible with those of the other species.
