The Vibrational Spectra and Structure of Inorganic Molecules. I. The Infra-Red Spectrum of F2O from 2.5 to 25μ

Abstract

The infra‐red spectrum of gaseous F2O has been obtained from 2.5 to 25μ at pressures of 10 mm to 600 mm Hg in a 10‐cm cell and at 600 mm Hg in a meter cell. All three fundamentals have been observed and identified. The fine structure of a ⊥ band was resolved and gave an estimate of the bond distance and apex angle as 1.38±0.03A and 101.5±1.5°, respectively. The upper and lower limits of the constants of a quadratic potential function with all possible interaction constants have been obtained.
