Figure 7.
Transient cw EPR spectra of ZnTPP‐trityl, H2TPP‐trityl and MgTPP‐trityl (from left to right) at the X‐band (9.75 GHz) and ZnTPP‐trityl (right) at the Q‐band (34.0 GHz) together with the best numeric fit to the experimental data. All spectra were recorded in frozen 2‐methyltetrahydrofuran solution at 80 K at about 1 μs after photoexcitation at 550 nm. The quartet state spectrum was simulated as the sum of net and multiplet components (red dotted lines) with different weights. The simulation parameters are indicated in the figure.
