Abstract

Time-resolved IR emissions were obtained for IR multiple-photon excitation/dissociation of CDF3 at 970 cm-1 in neat form and its mixtures with CHF3 and argon at moderate pressures. Enhancements in emission intensities were observed for CDF3 and DF on addition of argon. The bimodal exponential decay observed for both CDF3 and DF emissions in the neat photolysis of CDF3 changed into single-mode decay when the sample was irradiated in the presence of argon at a focal fluence of 95 J cm-2. The bimolecular rate constant for collisional deactivation of CDF3 by argon was 1.3 × 103 s-1 Torr-1. In situ selectivity factors were determined from the measurements of DF and HF emission intensities in the photolysis of 1:1 CDF3-CHF3 mixtures.
