Reactions of carbon atoms using crossed pulsed molecular beams
In the second year of the current funding period, we continued the study of the following reactions: C({sup 1}D) + H{sub 2} {yields} CH(X{sup 2}{Omicron}) + H, {Delta}H = {minus}6.0 kcal.mol{sup {minus}1}; C({sup 1}D) + HCl {yields} CH(X{sup 2}{Omicron}) + Cl, {Delta}H = 7.0 kcal.mol{sup {minus}1}; and C({sup 1}D) + HCl {yields} CCl(X{sup 2}{Omicron}) + H, {Delta}H = {minus}5.8 kcal.mol{sup {minus}1}. In particular, we concentrated on three issues: the use of two-photon photolysis of C{sub 3}O{sub 2} as a source of C({sup 1}D); the mechanisms of the above reactions and conditions for reliable LIF diagnostics for the CH radical. These studies involved solving several problems both in the generation of C({sup 1}D) and the determination of rotational, spin-orbit and {Lambda}-doublet populations in CH, but they are now nearing completion, and will be written up for publication in the summer. In the third year, we plan to concentrate on three topics: (1) the construction of an efficient laser ablation source for C({sup 3}P); (2) the study of the reaction of C({sup 3}P) with N{sub 2}O and detection of CN and NO products, and (3) a new direction in our lab: enhancement of endoergic reactions of C({sup 3}P) via vibrational excitation of molecular reactants.
