Scientific paper

The present steady state model of interstellar cloud chemical composition involves 1074 reactions among 80 species formed from H, C, N and O, and includes the heavy elements He, Mg, Si, Fe, and S, due to their role in the ionization equilibrium. The chemical balance equations are solved, together with a transfer equation, in a self-consistent way; the transfer equation is solved in each line of the Lyman band to obtain the photodestruction rate as a function of depth in the cloud. By taking all possible absorbers into account at each frequency, as well as the larger opacity for nonnormally incident photons, very efficient shielding is obtained, together with an H-H2 transition that is more rapid than that of previous models. The model provides the photodestruction rates and the densities of the chemical species as a function of position in the cloud.
