Figure 2.
FIG. 2. Long distance overview of the F[exc]-F[gnd] difference Fourier electron density maps resulting from green light illumination at 110 K contoured at 4.0 (a), red light illumination at 150 K contoured at 3.2 (b), and green light illumination at 170 K contoured at 3.4 (c). Positive electron density changes are colored blue, and negative electron density changes are colored yellow. More details of the trapping protocols are given in the text. Overviews of the difference density maps depicted in a and c can be found in stereo in Refs. 10 and 1, respectively.
