摘要：
The intramolecular electron transfer (ET) rates of the 1,3-dinitrobenzene radical anion in aprotic solvents were determined at various temperatures by means of ESR line-broadening method. The rates with negligible ion-ion interaction were determined in acetonitrile and N,N-dimethylformamide by addition of a cryptand. The obtained rates were 10 times or more compared with those in the presence of 0.1 mol dm(-3) supporting electrolyte. Simple adiabatic ET model was used for the examination of solvent dependence of the ET rates. (C) 2001 Elsevier Science B.V. All rights reserved.
