The reactions of laser ablated Group IV metal atoms with acetylene in excess argon have been studied using the matrix isolation infrared spectroscopic technique. The infrared spectra of the argon matrices (6-7 K) that result from the codeposition of the laser ablated metal atoms with $C2H2/Ar$ mixtures provide evidence for the presence of several new product species that arise from the metal atom activation of the acetylene C-H bond. These new species will be identified by their infrared spectra and the effects of $\mathrm{<mrow\; data-mjx-texclass="ORD">13</mrow>}C$ and D isotopic substitution in the precursor $C2H2$ molecule.
