Figure 4
Fourier maps of the four potential solutions for the two-dimensional model structure of Example 1. The maps were calculated with the Mathematical equation values and phases listed in Table A3, with A = B = 0° (solution S1), A = 0° and B = 180° (S2), A = 180° and B = 0° (S3), and A = B = 180° (S4). Visual comparison with the structure model in Fig. 3[link] shows that the maxima in Fourier map S4 correspond with the positions of the carbon atoms, and thus indicate the correct solution. When the locations of the peak maxima in map S4 are checked against those of the initial model, it is found that all four positions are within 0.04 Å of their correct position (see Table A5).
