Many of the molecules found in space are carbonaceous, that is, they have a carbon backbone in their structure. In addition, many of these molecules carry heteroatoms such as nitrogen and oxygen and also second row elements such as silicon. To date, four silicon-carbon molecules SiC_n (n=1-4) have been detected in space and several more by high-resolution spectroscopic techniques in the laboratory. Owing to their symmetry, many clusters of the form SiC_nSi (and linear C_n chains) are non-polar and hence have no pure rotational spectrum. In an effort to obtain the gas-phase spectra of these clusters in the infrared, we have started a dedicated laboratory program employing diode laser techniques and more recently an optical parametric oscillator-based spectrometer operating at 5μm, where many carbon- and carbon-silicon chains are expected to exhibit strong infrared-active vibrational modes. First results from targeted studies if the Si_2C_3 and C_6 clusters will be reported.
