摘要
The hydrogen atom abstraction reaction of the triplet pyrazine at low temperature was studied. Activation energies for pyrazyl stabilization and phosphorescence quenching agree with each other and are 2.1-2.3 kcal mol-1. This value shows the activation energy of the hydrogen abstraction reaction by the triplet pyrazine. The effect of the solvent cage is negligible in this case. © 1979 American Chemical Society.
