Comparison of 57Fe Davies ENDOR acquired at three major g-values for E4(4H) state trapped during Ar turnover of 57Fe enriched V70I12 and for E4(2H)* photogenerated from E4(4H) by irradiation with 450 nm laser diode at 12 K. “Goalposts” indicate response from one iron centered at half of its hyperfine coupling and split by 2ν(57Fe). Conditions: T = 2 K; microwave frequency, 34.81 and 34.90 GHz for E4(4H) and E4(2H)* correspondingly; t(π/2) = 40 ns, τ = 600 ns; TRF = 35 μs; repetition time, 100 and 25 ms; 200–400 scans.
