Description
Summary:	The effect of shock waves on the chemical structure of the interstellar clouds is studied. A model of molecular cloud has been assumed. The chemistry is investigated in a time dependent model. The present chemical network contains 56 species in 251 reactions to including molecules of the elements H, O, C, N, S, and Si. The results indicate that the calculated fractional abundance of the molecules NS, H2O, CN, NH, CO, and SO agrees well with the observations. The molecules OH, H2S, CS, H2CS, HS, NO, SiO, CH, CH2, CH3, HCO, C2, and HCN reach high postshock abundances. (Author)
