Abstract

Pulse radiolysis of N,N-dimethylaniline (DMA) in neutral aqueous solution shows formation of N-methylanilinomethyl radicals and radical cations in a ratio of 1:2. The precursor for the two radicals is the OH radical. The existence of the OH adduct of DMA is demonstrated using nanosecond time resolution. This adduct undergoes dissociation to hydroxide ions and radical cations with a rate constant of (7 ± 2) × 10⁶ s^-1. The radical cation absorbs at 465 nm with an extinction coefficient ε₄₆₅ of 4500 M^-1 s^-1.
