Scientific paper

The gas phase chemistry of silicon in dense interstellar clouds has been investigated using a pseudo-time-dependent model. Based on new ion-molecule reaction studies as well as on improvements in the knowledge of the thermochemistry of silicon-bearing species, the model contains approximately 300 gas phase reactions involving such species. Calculated abundances are presented for a number of silicon-containing molecules including those with carbon-silicon bonds. The results for a dark cloud with T = 10 K and n(H2) = 10,000/cu cm show that unless a very large depletion for silicon in the gas phase is assumed, the predicted SiO abundance is much larger than observed in such sources.
