Detection of interstellar hydrogen sulfide in cold, dark clouds.

open access: yesAstrophysical Journal, 1989
Interstellar H2S has been detected toward the cold, dark clouds L134N and TMC 1. Total column densities at the SO peak of L134N and the NH3 peak of TMC 1 are found to be about 2.6 X 10 to the 13th/sq cm and 7.0 X 10 to the 12th/sq cm, respectively. The results suggest that grain surface reactions may play a major role in the synthesis of H2S in cold ...

Chemical abundances in cold, dark interstellar clouds

Icarus, 1991
The Sun may well have formed in the type of interstellar cloud currently referred to as a cold, dark cloud. We present current tabulations of the totality of known interstellar molecules and of the subset which have been identified in cold clouds. Molecular abundances are given for two such clouds which show interesting chemical differences in spite ...

The two chemical phases of dark interstellar clouds [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 1992
We show that there exist two phases in the chemical equilibrium state of dark interstellar clouds, according to the local value of the density, n H , and cosmic ray ionization rate, ζ. For a given value of ζ, the ion-neutral chemistry at high density is driven by proton transfer with H 3 + while at low density charge transfer with H + dominates. The
