Raman spectra of iodine pentafluoride have been measured for the gas as well as for the liquid as a function of temperature. The intense polarized band which appears in the room temperature spectra of the liquid at 697 cm −1 and a weaker, previously unreported, band at 218 cm −1 are absent both from the gas spectra and from the elevated temperature spectra of the liquid. This indicates that these bands arise from the presence of polymers in the liquid state rather than from Fermi resonance.
