The reactive excited states of acridine and phenazine in solution: a flash photolysis electron spin resonance and chemically induced dynamic electron polarization study
Buckley CD., McLauchlan KA.
The free radicals formed on reaction of the excited states of acridine and phenazine with suitable hydrogen donors are produced in an electron-spin-polarized state. From the phases of their electron spin resonance signals it is concluded that, whilst acridine reacts through an excited singlet state, phenazine reacts through an excited triplet one. The precise nature of these states is discussed. © 1984.
