1From matrix IR absorption and Raman spectra in Ar Arkell, Reinhard, et al., 1965, Andrews and Raymond, 1971, Andrews, 1972. O'Hare and Wahl, 1970 suggest a corrected gas phase frequency of 1050 cm-1.
2Theoretical calculations O'Hare and Wahl, 1970.
3Indirectly from the difference between the electron impact appearance potentials of FO+ from FO and F2O Clyne and Watson, 1971 and the known heat of atomization of F2O; see also O'Hare and Wahl, 1970, Levy, 1972.
4Photoionization mass spectrometry of F2O Berkowitz, Dehmer, et al., 1973. See also O'Hare and Wahl, 1970.
