Magnetic-field effects on the photochemical kinetics of AtCry and EcPL. Transient absorption kinetic time profiles of (A) AtCry and (C) EcPL both recorded at 510 nm with and without a 28 mT applied magnetic field. (B) and (D) Differences between the two signals shown in (A) and in (C), respectively: ΔΔA = ΔA(28 mT) - ΔA(0). 200 ns boxcar smoothing was used to produce (B) and (D); no smoothing was used for (A) and (C). Experimental conditions: AtCry, 270 K in 60% (v/v) glycerol solution; EcPL, 250 K in 50% (v/v) glycerol solution. Similar traces for both proteins were observed at temperatures between 240 K and 275 K and glycerol contents between 25% and 65% (SI Appendix).
