FIG. 2. — PYP photocycle from a time-resolved crystallographer's perspective. The early intermediate I_T crosses over to pR₁ and I_CT in a hula-twist and a bicycle pedal motion, respectively. I_CT decays to pR₂. pR₂ and pR₁ both react to pB₁ that may decay directly to the dark state. At higher temperatures pB₂ accumulates in addition. Mechanism is simplified by omitting less important transition pathways; see Ref. 2 for a more comprehensive mechanism. Free energies of the barriers of activation are shown as determined from five-dimensional crystallography for several transitions.
