chemtools: Python toolbox for Computational Chemistry

Chemtools is a set of modules that is intended to help with more advanced computations using common electronic structure programs.

The main to goal was to enable convenient basis set manipulations, including designing and optimizing exponents of basis sets. To achieve that there are several modules abstracting various functionalities.

Currently there is support optimizing basis set (or doing general computations) with:

Getting Started

The best way to get started is to go over the tutorials illustrating the functionalities and giving examples of basis set optimization tasks.


Most convenient way to install the package is with pip

pip install chemtools
