The vibrational fundamentals and structures of novel germanium-carbon and mixed germanium-silicon-carbon clusters, formed by laser ablation and trapped in solid Ar, are currently under $investigation.a$ Vibrational fundamentals and ground state geometries are characterized by comparison of Fourier transform infrared measurements of vibrational frequencies and $\mathrm{<mrow\; data-mjx-texclass="ORD">13</mrow>}C$ isotopic shifts for the matrix isolated clusters with the predictions of density functional theory (DFT). Linear $GeC3Si$ has been detected, the first $GejCmSin$ species to be observed optically, and its $\nu 1$ fundamental identified at $1939.0cm-1$. The results are in excellent agreement with DFT predictions. Additional results and assignments for $GenCm$ clusters will be reported.
