PS equilibrium relaxation monitored by UV–Vis absorption spectroscopy. (a) Time-dependent series of spectra recorded at 2 Hz from 0 s (red spectra) to 100 s (blue spectra) after the end of blue-light illumination of a solution of LOV2. (b) Time evolution of the absorbance at 390 nm of the solution spectra shown in (a), modelled with a monoexponential decay (red curve) with τ = 6.0 s. (c) Time-dependent series of spectra recorded at 2 Hz from 0 s (red spectra) to 300 s (blue spectra) after the end of blue-light illumination of a crystal of LOV2. (d) Time evolution of the absorbance at 390 nm of the solution spectra shown in (c), modelled with a monoexponential decay (red curve) with τ = 40 s.
