Fig. 12: Structural changes in bR resulting from photoexcitation at 110 K. Overview of the (Fexc - Fground) difference electron density maps (yellow: negative, blue: positive density) contoured to 3.5 ( = r.m.s. electron density for the unit cell) and overlaid on the ground state bR model. At this contour level most changes are clustered in the vicinity of the retinal.
