| Popis: | We have constructed a chemical reaction system in a contracting interstellar cloud. In paper (I) we have presented the details of the physical and chemical scheme and the method of solution. The results of our chemical model produce fractional abundances of H2CO, CO, OH, H2O, SO and OCS which are in good agreement with the results of observations. On the other hand, the results of chlorine-bearing species are not in agreement with those of the observations. The calculated abundances of H2CO, CO, OH, H2O, SO, OCS and Cl+ are in agreement with the results of previous theoretical studies. |
