Ionization of carbon disulfide/ozone mixtures in atmospheric gases

An ionic route to the CS2 degradation was studied by mass spectrometric and theoretical methods. Ionized mixtures containing carbon disulfide and ozone prove an effective source of S2+andSO+ ions, formed by remarkable molecular reorganization and open to further reactions with ozone and surrounding species. Both the O-transfer and dissociative oxidation processes, typical of the O3 reactivity in ionized mixtures, were observed.
