Infrared Spectrum of CF2

A low-temperature infrared study of the photolysis products of CF2N2 in inert matrices has yielded the three vibrational fundamentals of the species CF2, at 668, 1102, and 1222 cm—1. Supplementary ultraviolet observations have confirmed the presence of CF2 in high concentration. Detection of the stretching fundamentals of 13CF2, present in natural abundance, has permitted an estimate of the FCF angle. The thermodynamic properties of CF2 have also been estimated. CF2 appears not to react with CO or with CO2 in a matrix environment.
