ZINDO is a semi-empirical electronic structure program that has been parameterized for spectroscopic properties of molecules. It provides a number of model Hamiltonians that, depending upon the desired property, can be chosen by the user.
One can explore either ground state or excited state properties including UV-visible spectra, stationary geometries of molecules, or transition states of chemical reactions. Due to the approximate nature of these Hamiltonians, the time required to run a ZINDO calculation is only a fraction of that required by first principles programs. This method can be applied to a wide range of molecules including organic, inorganic, polymer, and organometallic compounds. ZINDO offers certain unique capabilities not available in other semi-empirical packages.
