摘要

A hitherto unknown,atmospherically relevant,isotope-exchange reaction was studied in ionised gaseous mixtures containing carbon dioxide and monoxide.The mechanism of the O exchange,proceeding over a double-minimum potential-energy surface,was positively established by mass spectrometric and theoretical methods that also allowed the identification and characterisation of the C_2O_3~+ intermediate.The increase of internal energy displaces the observed reactivity towards an endothermic reaction path that involves only CO_2 and represents an indirect route to the dissociation of carbon dioxide.
