Abstract
An FTIR study of the products of the vacuum uv photolysis of $CH_{3}CCH$, methylacetylene and its partially and fully deuterated istopomers has revealed new information on the vibrational spectra of a variety of tricarbon hydride radicals, $C_{3}H_{n} <n \leq 5$). New vibrations for $C_{2}H$, propynylidyne; $C_{3}H_{2}$, cis- and trans-propenediylidene, and $C_{3}H_{3}$, cyclopropenyl are proposed. Also observed are the cyclopropenylidene, vinylidenecarbene, and propargylene isomers of $C_{3}H_{2}$, and the $C_{3}H_{3}$, allyl radical. On the basis of isotopic data previous vibrational assignments are confirmed, and in some cases, revisions are suggested
