libreta: Download   Obara-Saika


libreta is a C++ library for the evaluation of molecular integrals over both segmented and general contracted Gaussian type orbitals (GTOs). It is written in a black-box way that one can use it without knowing anything inside. With libreta, you can easily set up your own quantum chemical algorithm! Currently the following types of integrals are supported:
