In this paper we present calculated fractional abundances in dense interstellar clouds for selected atomic and molecular species using three different homogeneous, pseudo-time-dependent models discussed by Bettens, Lee, & Herbst (1995): the new standard model, the new neutral-neutral model, and model 4. We have run each model with 3 different hydrogen densities - 10^3^, 10^4^, and 10^5^cm^-3^ - and two temperatures - 10K and 50K. "Low metal" elemental abundances have been used for all three models; the new standard model has also been run with "high metal" abundances.
