Infrared chemiluminescence from the reaction of hydrogen atoms with fluoroethylenes

Abstract

The reactions of hydrogen atoms with the fluoroethylenes C₂F₄, C₂HF₃, C₂H₂F₂ and C₂H₃F were found to produce vibrationally excited HF†; (up to v′= 3). The variation of the emission intensity from the excited HF†; has been studied at various pressure in the presence of Ar or He. From these studies the relative rates of formation of HF†; into the individual vibrational levels have been obtained. The simple Golden Rule model of M. J. Berry has been applied to these results.
