Notes:
The 5-10-dihydrophenazine and the 5-methyl-10-hydrophenazine free radical cations have been prepared at room temperature by photolysis of phenazine and 10-methylphenazine, respectively, in acidic ethanol solution. Both radicals exhibit very intense visible absorptions which have permitted the excitation of their resonance Raman spectra. Raman spectra have been recorded using various laser exciting lines, and excitation profiles for both systems have been determined. The parent-to-radical wavenumber shifts observed for each species have been interpreted in terms of the structural changes brought about by radical formation.
