Spectroscopic characterization of the dark and light states of AtPhot2LOV2. (a) Absorption spectra of the dark state (blue) and the blue-light-induced photoadduct (purple) recorded from crystals at room temperature. (b) Evolution of UV–Vis absorption spectra recorded with increasing X-ray doses from an AtPhot2LOV2 crystal at 100 K (inset: dose-dependent evolution of the absorbance at 490 nm, illustrating the X-ray-induced relaxation to the dark state).
