INFRARED LASER ENHANCED REACTIONS: O3 + SO
Vibrationally excited ozone, O3 produced by CO2 laser radiation was found to react with SO significantly faster than thermal ozone via the chemiluminescent reaction process O3 + SO to SO2 (singlet B(1)) + O2 (triplet Sigma (g)). The vibrational rate enhancement of this reaction was 2.5 plus or minus 0.6 at 300 K. This represents the use of 27% of the available vibrational energy to promote the reaction, based on a model assuming involvement of a single vibrational mode. The laser enhanced chemiluminescence measured from 260 to 450 nm was found to exhibit a 630 plus or minus 200/cm blue shift. This is interpreted as a partitioning of the available vibrational energy of O3 in the vibrational manifold of the SO2 (singlet B(1)) product.
