Time-dependent photoreduction of AXCP crystals. Photoreduction was not observed for laser power densities of 1.6 and 4.0 mW mm−2. Laser power densities of >4.0 mW mm−2 result in reduction of the haem. Data points for power densities where photoreduction was observed have been fitted to a single exponential decay function. Data for an extended exposure time are included for a power density of 9.8 mW mm−2 to demonstrate almost complete interconversion to the ferrous form.
