a, Q-band FF trESR on frozen 200 μM toluene solutions, 1–4 μs after excitation with 0.4 mJ 600 nm pulses. The lineshape is analogous to the X-band FF spectra, with no level crossings detected at fields up to 1.3 T. b, Magnetophotoselection in X-band FF trESR. Dilute toluene solutions at 80 K following 0.7 mJ 600 nm excitation at 40 dB microwave attenuation. Signals normalized by total area. No selection observed for z transitions, and opposite dependence for TTM-1Cz-An and TTM-1Cz-PhAn seen for x/y transitions. c, Arrhenius plot of quartet polarisation inversion dynamics in TTM-1Cz-An.
