MICROWAVE SPECTRUM STRUCTURE AND DIPOLE MOMENT OF DIFLUOROPHOSPHINE OXIDE

The microwave spectra of HF2PO, DF2PO, and HF2P18O have been analyzed. The structural parameters are d(PH) = 1.387 ± 0.01 Å, d(PF) = 1.539 ± 0.003 Å, d(PO) = 1.437 ± 0.006 Å, ZHPO = 117.9 ± 2°, ZFPO = 116.3 ± 1°, ZHPF = 101.9 ± 1. 5°, and ZFPF = 99.8±0.5°. The dipole moment was evaluated as 2.65 ± 0.03 D. © 1968, American Chemical Society. All rights reserved.
