9. Transient absorption was performed in DMSO using a Spex Model 1877 triple spectrograph with a PAR Model 1420 OMA gated detector and PAR Model 1463 controller. The samples were made anaerobic via three freeze/pump/thaw cycles. Excitation at 416 nm was provided by Raman shifting the output of a tripled Nd-YAG laser Model DCR-2 in a high pressure hydrogen gas cell. The probe light source was a PTI Model 220 75 W xenon arc lamp.

12. •+ has been shown to absorb maximally at 410 nm (Buranda, T.; Soice, N.; Lin, S.; Larson, R.; Ondrias, M. J. Phys. Chem. 1996, 700, 18868-18874). Therefore, an appreciable resonance enhancement for the porphyrin π-cation radical of 1 and 2 may be expected with a 416 nm probe.
13. Raman shifts for the excited state transient of 2 are virtually identical to 1.
