The Mass and Microwave Spectra, Structures and Dipole Moments of the Isomers of Sulfurmonofluoride

摘要

Two isomers of S2F2 were prepared by heating AgF and S. The relative mass spectral cracking patterns of both isomers are reported. For one isomer, microwave transitions for the S32 = S32F2, S32 = S32 F2 and S34 = S32F2 species were obtained. The structure was determined to be pyramidal S = SFp with d(SS) = 1.860 + 0.015 A , d(SP) = 1-598 + 0-012 A , SSF = 107.5° + 1° , and Z5SF = 92^5° + 1°. The dipole moment was 1.03 t 0.03 D. For the second isomer, microwave transitions for the FS32 S32 F and FS32S34F species were obtained. The structure was determined to be nonplanar chain FSSF with d(SS)= 1.888 0.01 A. , d(SF) = 1.635 0.01 A ,
