Dissociative Ionization and Metastable Ions of Nitrobenzene and Nitrobenzene-d₅

Abstract

The kinetica energy released on the loss of CN02 from nitrobenzene and deuterated nitro benzene ions in the second field-free region shows that this loss does not occur as a single-step process.The apparent heat of formation of the QH5 ion is found to be 270.85 kcal mol-1, which is consistent with the ion having the cyclic structure.
