The charge exchange mass spectra of a selection of C5-C7 ketones have been measured using [CS2]+˙, [COS]+˙ and [N2O]+. as reagent ions. The low energy charge exchange with [CS2]+˙ or [COS]+˙ provides simple primary ion mass spectra, which readily permit structure elucidation in contrast to metastable ion spectra. In several cases, isomer distinction is easier from the charge exchange mass spectra than from the electron impact mass spectra. The energy transfer from [N2O]+˙ is sufficiently high for complex spectra resembling electron impact mass spectra to be obtained.
