Molecular Abundances in B68
J. Di Francesco, M. R. Hogerheijde, W. J. Welch +1
Abundances for C18O, CS, NH3, H2CO, C3H2, and N2H+ and upper limits for the abundances of 13CO and HCO+ are derived for gas within the Bok globule B68 using our own BIMA array data…

Dense gas in nearby galaxies XI. H_2CO and CH_3OH: Molecular abundances and physical conditions
S. Huettemeister, R. Mauersberger, C. Henkel
Multilevel observations of formaldehyde (H_2CO) and methanol (CH_3OH) toward the nearby spiral galaxies NGC 253, Maffei 2, IC 342, M 82 and NGC 6946 are presented. H_2CO was detect…
