Pulse Radiolysis of Aqueous Methylhydrazine Solutions

Pulse radiolysis of aqueous methylhydrazine solutions under different conditions was studied. The main characteristic peaks in these transient absorption spectra were attributed and the build-up/decay trends of several transient species were investigated. The reaction product of •OH radical and methylhydrazine is CH₃•NNH₂ radical with a rate constant of (2.4±0.1)×10¹⁰mol^-1•L•s^-1. The reaction product of e_aq^- and methylhydrazine is CH₃•NHNH₂ radical with a rate constant of (2.7±0.2)×10⁸ mol^-1•L•s^-1.
