ChemTools is a free and open source Python library for interpreting the results of quantum chemistry calculations. The goal of ChemTools is to provide a toolbox by which the quantitative output of electronic structure theory calculations can be expressed in chemical language. ChemTools provides easy-to-use core functionality to compute fundamental descriptors of conceptual quantum chemistry, together with a flexible set of utilities allowing scientists to easily test their own discoveries.
