Linear and cyclic oxocarbons, (CO)n-m (m=0,1,2... n=2,3,4...) have been known as a new series of compounds since 19601. These highly conjugated species are of great importance in a variety of fields like organic and analytical chemistry, biochemistry and pharmacology and solid state chemistry 2-4.

The existence of radical anions, for these species was predicted 2,3 almost two decades ago but only a little is known about them. The C2O2 radical anion (I) has been considered as a precursor for a long sought after ethylene dione via neutralisation-reionization technique5.

The formation of the following species along with their collision induced fragmentation, neutralisation-reionization and theoretical investigations will be discussed.

The radical anions I and II have been formed for the first time where as III has been reported before6.
