Microwave Spectra and Molecular Structures of POF3, PSF3, POCl3, and PSCl3
Abstract
From measurements of pure rotational transitions in the microwave region the following B0 values in Mc/sec were determined: 4594.25±0.04 for PO16F3, 4395.27±0.20 for PO18F3, 2657.63±0.04 for PS32F3, 2614.73±0.04 for PS33F3, 2579.77±0.04 for PS34F3, 2015.20±0.05 for PO16Cl335, 1932.38±0.08 for PO16Cl337, 1402.64±0.05 for PS32Cl235, 1355.72±0.05 for PS32Cl337, 1370.13±0.05 for PS34Cl335. With the aid of electron diffraction results the molecular structures have been determined as follows: for POF3, dPO=1.45±0.03A, dPF=1.52±0.02A and ∠FPF=102.5°±2°; for PSF3, dPS=1.87±0.03A, dPF=1.53±0.02A and ∠FPF=100.3°±2°; for POCl3, dPO=1.45±0.03A, dPCl=1.99±0.02A and ∠ClPCl=103.6°±2°. The structure of PSCl3, determined entirely from microwave data is: dPS=1.85±0.02, dPCl=2.02±0.01 and ∠ClPCl=100.5°±1°.
