INFRARED LASER ENHANCED REACTIONS: V TO V AND V TO T ENERGY TRANSFER IN THE O3-SIF4-O2 SYSTEM

Rapid V to V energy transfer between SiF4 and O3 has been observed following CO2 laser excitation of either O3 or SiF4. In experiments employing the P(32) transition the V to V transfer to O3 and subsequent reaction of O3(+) with NO were used to obtain the rate constant of V to T deactivation of SiF4 by O2. Fractional modulation measurements of the chemiluminescence generated by the O3 + NO reaction were used in experiments employing the P(30) transition to obtain a rate constant for the V to V energy transfer between O3(+) and SiF4.
