ChemTools

About

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.
