Abstract: The matrix isolation technique has been coupled with excimer laser technology for the identification and characterization of intermediates of the reactions of oxygen atoms with acetylene and propyne. 193 nm laser irradiation of argon matrices containing $O_{2}$ leads to the production of 0 atoms, which subsequently react with the trapped alkyne. Two sets of products are observed, one coming from the reaction of a single 0 atom with the alkyne, and the second set requiring two 0 atoms. Irradiation of matrices containing $N_{2}O$ as a single 0 atom photolytic source allow distinction between these two sets. Similar results were obtained with both in situ and in vivo irradiation. The results for $0 + C_{3}H_{4}$ are interpreted in terms of an undetected ethylidene intermediate.
