ZINDO


ZINDO is a semi-empirical quantum chemistry method used in computational chemistry. It is a development of the INDO method. It stands for Zerner's Intermediate Neglect of Differential Overlap, as it was developed by Michael Zerner and his coworkers in the 1970s. Unlike INDO, which was really restricted to organic molecules and those containing the atoms B to F, ZINDO covers a wide range of the periodic table, even including the rare-earth elements. There are two distinct versions of the method:
The original BIGSPEC program from the Zerner group is not widely available, but the method is implemented in HyperChem, ORCA, in part, in Gaussian, and in SCIGRESS.
To obtain good results, it is frequently necessary to fit the parameters to a given molecule, thereby making it ideal only in semi-empirical calculations.
