The infrared spectrum and vibrational intensity of gaseous dioxygen difluoride (foof)

Abstract

A complete absorption spectrum of gaseous dioxygen difluoride (FOOF) was obtained using a very long pathlength, temperature-programmable cell and an FT-IR spectrometer. All six fundamental vibrational frequencies were deduced from three fundamental bands and four binary combination bands. A significant deviation of the v frequency is observed from the matrix studies of solid FOOF. The absolute vibrational intensities of observed bands are reported.
