Ra. Brownsword et al., INFRARED-EMISSION FROM THE REACTION OF CHF ((X)OVER-TILDE-(1)A') WITHNO, Journal of physical chemistry, 100(12), 1996, pp. 4840-4847
Infrared emission has been observed from the reaction of the CHF ((X)
over tilde(1)A') radical with NO (X(2) Pi). The carbene radical was fo
rmed by infrared multiphoton dissociation (IRMPD) of either the CH2FCl
or the CH2F2 precursor, and emission in the 1850-4500-cm(-1) region w
as observed by a time-resolved Fourier transform infrared (FTIR) techn
ique. Emissions have been identified from the HF product of the reacti
on and from Species produced by the subsequent reaction of the NCO rad
ical product with NO. The HF was found to possess more than a statisti
cal share of the available energy in vibration. Addition of D-2 to the
system results in DF formed from the reaction of F atoms, and compari
son of the HF/DF emission intensities has allowed the relative branchi
ng ratio of the CHF + NO reaction forming HF and F products to be 0.6
+/- 0.04:0.4 +/- 0.03.
