Microwave spectrum and dipole moment of methyldifluorophosphine--borane

  • 1. Michigan State Univ., East Lansing

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)
