The rotational spectra of the normal and 13C isotopomers of difluorodimethylsilane have been measured by molecular beam Fourier-transform microwave (FTMW) and free-jet absorption millimeter-wave (FJ-AMMW) spectroscopy. Each rotational transition is split into several component lines due to the two methyl groups internal rotations. The corresponding V3 barrier has been determined to be 5.256(3) kJmol1. A r0 structure of the heavy atoms skeleton has been obtained. The silicon atom lies—accidentally— on the center of mass of the molecule.

Abstract
The rotational spectra of the normal and 13C isotopomers of difluorodimethylsilane have been measured by molecular beam Fourier-transform microwave (FTMW) and free-jet absorption millimeter-wave (FJ-AMMW) spectroscopy. Each rotational transition is split into several component lines due to the two methyl groups internal rotations. The corresponding V3 barrier has been determined to be 5.256(3) kJmol1. A r0 structure of the heavy atoms skeleton has been obtained. The silicon atom lies—accidentally— on the center of mass of the molecule.File in questo prodotto:
