Secondary ion mass spectra of neat solid CO2, COS and CS2 and of CO2 diluted in solid argon were measured as a function of the nature and energy of the primary ions (He+, Ne+, Ar+, Kr+, Xe+, 1.0-4.5 keV). All of the solids produced a rich variety of positive and negative secondary ions. Many of these have masses considerably in excess of the molecular weight of the parent molecules, particularly with primary ions of large momentum. Carbon dioxide produces well-defined cluster series with CO2 as the solvating unit. Carbonyl sulfide and carbon disulfide yield a complex pattern of positive and negative cluster ions.
