A study of interstellar molecules is presented. It includes two areas of interest; one area uses the ability of molecules to act as probes of the physical conditions in the cold, dense, opaque component of the interstellar medium, and the physical properties of this component of the interstellar medium are summarized. The other deals with the chemistry of interstellar molecules, and their recent aspects are reviewed. Gas-phase chemistry, shock chemistry, and grain surface chemistry are discussed; no present observations suggest that surface reactions are relevant, but neither can they be ruled out. The ion-molecule reactions are clearly operative, at least for simple species; chemical isotope fractionation is reviewed, concluding that the complexities of the chemistry allow no cosmological conclusions to be drawn from observations of deuterium in interstellar molecules. The presence of C-13 in interstellar molecules permits an estimate of the C-12/C-13 ratio which is consistent with the current concepts of the nucleosynthesis history of the Galaxy.
