Abstract
Well resolved vibrational spectra of $C_{n}$, and $Si_{m}C_{n}$ clusters have been produced by trapping products from the pulsed laser evaporation of pure carbon and silicon/carbon rods in Ar at 10 K. Controlled thermally induced diffusion in the matrix has enabled the growth of large clusters. To assist in the analysis of vibrational spectra extensive carbiin-13 isotopic shift measurements have been made. Objectives in this work are the identification of linear $C_{n}$ clusters with n ?` 9 or cyclic $C_{n}$ clusters, and $Si_{m}C_{n}$ clusters consisting of long carbon chains with terminal Si atoms.
