Reactions of O atoms and OH radicals with acetylene and methylacetylene were studied in high-intensity room-temperature crossed molecular beams. Products were detected using photoionization mass spectrometry. Major and minor observed reactive chnnnels were assigned on the basis of the identity of the products observed and the magnitudes of the product ion signals. The numbers of major observed reactive channels are two for O + C/sub 2/H/sub 2/, one for OH + C/ sub 2/H/sub 2/, seven for O + C/sub 3/H/sub 4/, and four for OH + C/sub 3/H/sub 4/ . Details on reaction dynamics were obtained using deuterated compounds and are discussed. Evidence is presented for several types of mechanisms including abstraction, displacement, and addition followed by decomposition.
