Many results of ab initio investigations are not easily accessible for interpretation. While energies can be interpreted in a straightforward manner, this is not the case for the electronic structure: wavefunction, electron density and derived properties do not directly correspond to chemical concepts. The field of electronic structure analysis (ESA) now aims at deriving quantities that make the connection between the delocalized electronic structure resulting from an orbital-based computation and local chemical concepts like Lewis structures, chemical bonds or charge distributions. The field of ESA is vast and only a few methods have been used for AS-ALD up to now. However, the potential is large and thus some methods are briefly presented that can deliver insights in the field.
