Hypofluorous acid: Infrared spectrum and vibrational potential function

Abstract

Photolysis of mixtures of fluorine and water suspended in a nitrogen matrix at 20 and 14°K produces several new infrared absorptions. Growth and diffusion studies, isotopic labeling, and normal coordinate analysis help to assign bands at 3483, 1393.0 and 884.0 cm −1 to HOF. A band at 3777 cm −1 is attributed to HF hydrogen—bonded in the same matrix cage to HOF. The HOF force field calculated by normal coordinate analysis shows that the bonding is similar to that in H 2O and F 2O.
