Chemical Analysis

Several analysis tools in ADF offer the possibility of gaining detailed understanding of the chemical problem at hand. These methods stress the underlying philosophy that the Kohn-Sham orbitals in DFT can be used for a quantitative MO theory. The ADF-GUI modules, such as ADFlevels and ADFview, make these analysis options readily accessible.
