The gas‐phase, ion molecule reaction between C 3 O 2 +. and C 3 O 2 has been studied by both double‐focusing and ion trap mass spectrometry, rationalized by the formation of a dimeric, odd electron cation [C 6 O 4 ] +. which decomposes extensively through sequential CO losses giving rise to [C 5 O 3 ] +. and [C 4 O 2 ] +. ions. The thermodynamics of this process have been investigated by means of ab initio calculation performed on the above species using different basis sets (STO‐3G, 3‐21G and 6‐31G * ).
