    • Analysis of the gradient field of the ELF enables one to locate its attractors (the local maxima) and the corresponding basins. There are basically two chemical kinds of basins. The core basins, labeled by C(atom symbol), which encompass nuclei with Z > 2, and the valence basins V(list of atoms) which may be common to more than one atom. Valence basins are thus characterized by their synaptic order, that is, the number of core basins with which they share a common boundary. A proton located in a valence basin is counted as a formal core, and thus increases the synaptic order of the basin by 1. Mono-, di-, or polysynaptic basins correspond to lone-pair, bicentric, and polycentric bonding regions, perspectively.

    • Note
    • The localization domains, that is, the regions where the ELF value is greater or equal to a given threshold, are called irreducible when they contain just one attractor or basin, and are called reducible otherwise. The reduction of reducible domains is a process that gives insights on the nature of the basins.
