Infrared, Raman spectra and vibrational assignment of (PF2)2O
1978
Abstract The IR spectra of gaseous and solid (PF 2 ) 2 O has been recorded from 80 to 1200 cm −1 . The Raman spectra of gaseous, liquid and solid (PF 2 ) 2 O have also been obtained (30–1000 cm −1 ). The spectra of the fluid phases indicate the presence of at least two conformers. The spectrum of the solid phase can readily be interpreted on the basis of a single conformer possessing a symmetry lower than C 2v . A vibrational assignment is proposed for all normal modes except the PF 2 torsions. The results are compared with similar data of related compounds. There appear to be two molecules per primitive cell based upon the low-frequency Raman data.
