Abstract
A particularly useful constraint for models of CH+ formation in inters tellar clouds is knowledge of the amount of CH associated with CH+ syn thesis. For lines of sight with no detectable CN absorption, this colu mn of CH can be inferred through a combined analysis of C I excitation and simplified chemical models. The approach is applied to data for t wo lines of sight, those toward 23 Ori and beta(1) Sco, for which N(CH )/N(CH+)less than or equal to 0.110.
