The Uppsala Quantum Chemistry (uquantchem) package is a program designed to solve the non-relativistic Schrödinger equation for atoms and molecules using gaussian basis sets.

The program has been written in Fortran 90 by Petros Souvatzis and for the moment the following capabilities have been implemented:

The UQUANTCHEM program  can be obtained free of charge by clicking on the download button below, or through Github


Unfortunately there is for the moment no guarantee that the program is free from bugs, thus be vigilant and always question weather your results seem physically sound or not.
