THE MICROWAVE SPECTRUM AND STRUCTURE OF METHYLPHOSPHINE BORANE
Publisher:
Ohio State UniversityAbstract:
The structure of methylphosphine borane has been determined from the moments of inertia of the following isotopic species: ($CH_{3})H_{2}$ $PBH_{3}$, ($CH_{3}$) $H_{2} P^{10}$ $BH_{3}$, ($CH_{3}$)$H_{2}$ $PBH_{2}$ $D_{3}$, ($CH_{3}$)$H_{2} PBH_{2}$ $D_{a}$,($^{13}$ $CH_{3}$)$H_{2} PBH_{3}$, ($CH_{2}$ $D_{a}$) $H_{2}$ $PBH_{3}$, ($CH_{2}$ $D_{a}$)$H_{2}$ $PBH_{3}$, and ($CH_{3}$) $HDPBH_{3}$. The borane and the methyl groups are both staggered with respect to the PH bonds. The parameters which involve the central phosphorus atom are: [FIGURE] The dipole moment was evaluated from Stark shifts: $\mu_{a} = 4.35$D., $\mu_{b} = 1.65$D., and $\mu_{T} = 4.65 \pm 0.05$D.""
