## It is shown that a high power infrared iaser can enhance a chemical reaction (by lowering the activation energy) even if the reactants are infrared izctive.

โฆ Synopsis
Reactions of CH2F2 excited in its C-F stretching mode by a TEA CO 2 laser have been investigated. Chemical reactions of the excited species in the neat show evidence of the difluorocarbene radical involvement. Reactions with molecular chlorine display at least two distinct mechanisms at different pressure regimes. Comparisons are made with other uninlolecular dissociations and bimolecular reactions induced by multiphoton absorptions from similar laser sources.

The laser-induced decomposition of a solid azido polymer (GAP) is reported. A TEA CO 2 laser (tunable in the 920-1080 cm -1 range) is used and the dissociation yield is shown to correlate with the one photon absorption spectrum, although about 15 photons per molecule are required to break the weakes
