Microwave spectrum and dipole moment of methyldifluorophosphine--borane
Description
The microwave spectra of CH3PF2.11BH3, CH3PF2.10BH3, CH3PF2.11BD3, and CH3PF2.10BD3 were assigned. Stark effect measurements gave the following values for the dipole moment and its components: μ/sub a/ = 3.52 (5) D, μ/sub b/ = 1.76 (5) D, μ/sub c/ = 0.0 D, and μ = 3.94 (5) D. The absence of resolvable internal rotation splittings in the ground state yields lower limits of about 2000 cal/mol for the barriers to both CH3 and BH3 group internal rotation. By judicious transfer of structural parameters from related molecules r(P--B) was estimated to be 1.84 +- 0.02 A. (auth)
