Figure 3
(a) Slice through Fobs, a Fourier map computed from the observed structure factors phased on the refined atomic coordinates. The slice shows the nuclear scattering density in the ac plane at b = 0.75; positive maxima correspond to C, N and O atoms, whereas negative minima correspond to H atoms. A drawing of the structure in this plane is shown in Fig. 5. (b) Electron density in the same plane as Fig. 3(a) calculated by VASP at zero pressure and temperature.
