Herbst, E., S. Green, P. Thaddeus, and W. Klemperer, 1977: Indirect observation of unobservable interstellar molecules. Astrophys. J., 215, 503-510, doi:10.1086/155381.

It is suggested that the abundances of neutral nonpolar interstellar molecules unobservable by radioastronomy can be systematically determined by radio observations of the protonated ions. As an example, observed N2H+ column densities are analyzed to infer molecular nitrogen abundances in dense interstellar clouds. The chemistries and expected densities of the protonated ions of O2, C2, CO2, C2H2, and CH4 are then discussed. Microwave transition frequencies for HCO2+ and C2H3+ are estimated, and a preliminary astronomical search for HCO2+ is described.
