Figure 1
Electrostatic potential (e Å−1) of the static charge density of DL-serine, derived by XDPROP (Volkov et al., 2006) from the multipole model AH(20), and mapped on the static electron density isosurface at 0.5 e Å−3. (a) ESP for a single molecule. (b) ESP for a cluster of 3×3×3 unit cells. The central unit cell is shown. The single molecule in (a) corresponds to the molecule in the lower-right corner of the unit cell in (b). |
