MICROWAVE SPECTRUM, INTERNAL BARRIER, MOLECULAR STRUCTURE AND DIPOLE MOMENT OF DISILANYL FLUORIDE.
Abstract
The microwave spectra of five isotopic species of disilanyl fluoride (Si2H5F) were studied in the region 12-38 Gc/sec. Several of the ground state transitions are split into doublets, some into triplets, due to the coupling of internal and overall rotation. Analysis of the splittings gives a barrier value V-3 = 1048 plus or minus 40 cal/mole. Rotational constants were determined for molecules containing silicon-28, -29 and -30 isotopes in each positions, and were used to calculate the structure. Stark effect measurements yield mu-A = 0.934 D, mu-B = 0.850 D and a total dipole moment mu = 1.26 plus or minus 0.01 D inclined at an angle of 10 degrees to the SiF bond. (Author)
