Figure 3.
Photodissociation of cyanide. A difference Fourier map calculated between data sets obtained in the dark and under continuous illumination from a red laser is superimposed on the ball-and-stick model around the haem group. Blue and red indicate newly appeared and the diminished densities, respectively (contoured at [plus minus]3[sigma]). (a) 5 mM KCN pH 6.8. (b) 50 mM KCN pH 9.7.
