Abstract: | The IR spectra of gaseous and solid (PF2)2O has been recorded from 80 to 1200 cm?1. The Raman spectra of gaseous, liquid and solid (PF2)2O 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 C2v. A vibrational assignment is proposed for all normal modes except the PF2 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. |
