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. Acta Crystallogr Sect F Struct
