The reaction character of m/z 183 and 184 ions generated from ion-molecule reaction of toluene under self-chemical ionization was studied using Collision-Induced Dissociation (CID). The results show that the m/z 183 and 184 ions have several transition state structures, such as diphenyl methane derivative, α-bond structure formed between toluene and tropylium, π-complex formed between toluene radical ion and toluene and π-complex consisted of benzyl ion and toluene.
