Direct measurements of the rate constants for the collisional removal of CFCl((X) over tilde(1)A’(0,1,0)) and CFCl-((X) over tilde(1)A’(0,0,0)) by ethylene (C2H4), propene (C3H6), 1-butene (1-C4H8), isobutene (i-C4H8), and 1,3-butadiene (C4H6) are presented. CFCl((X) over tilde(1)A’(0,n,0)) species were prepared by infrared multiple photon dissociation, IRMPD, of the CHFCl2 precursor and their population time evolution followed by probing the transition CFCl((A) over tilde(1)A "(0,1,0)) <-- CFCl((X) over tilde(1)A’(0,n,0)) with a tunable dye laser. Removal rate constants of CFCl-((X) over tilde(1)A’(0,1,0)) by ethylene and propene, independent of CO2-laser fluence, have been measured as follows : 0.85 +/- 0.06 and 1.18 +/- 0.09 (in units of 10(-12) cm(3) molecule(-1) s(-1)). Removal rate constants by 1-butene, isobutene, and 1,3-butadiene are found to be fluence dependent with threshold fluence limits of 1.30 +/- 0.17, 1.60 +/- 0.18, and 0.70 +/- 0.07 (in units of 10(-12) cm(3) molecule(-1) s(-1)). For CFCl((X) over tilde(1)A’(0,0,0)) the removal rate constants for ethylene and propene, and those dependent on CO2-laser fluence, namely, 1-butene, isobutene, and 1,3-butadiene, are found to be as follows (in units of 10(-13) cm(3) molecule(-1) s(-1)) : 3.4 +/- 0.5, 2.2 +/- 0.3, 1.6 +/- 0.4, 0.9 +/- 0.2, and 2.5 +/- 0.5. A discussion of the influence of the intermolecular potential well depths of the reactants and their vibrational spacing on the removal rates is also presented.
