Electron Spin Resonance of the Radical Complexes (NO2)2, (t-BuO)2, and (CH3)2 in an Argon Matrix at 10K.

摘要

In the present electron spin resonance (esr) study nitrate esters or t-butyl peroxide in an inert gas (1:100) are pyrolyzed to produce the monoradicals NO2, CH3, and t-BuO. The pyrolysis products and inert gas are collected as a solid at 10K. In the solid phase some of the monoradicals associate to form the radical complexes (NO2)2, (CH3)2, and (t-BuO)2. The integrated intensity of the complex in these cases is always about four orders of magnitude less than the integrated intensity of the monoradical. This fact tends to support the possibility that the complex will be formed from any monoradical that reaches a certain threshold concentration. (Author)
