How To Install libr12 on CentOS 7
Introduction
In this tutorial we learn how to install libr12 on CentOS 7.
What is libr12
libr12 computes types integrals that appear in Kutzelnigg’s linear R12 theories for electronic structure. All linear R12 methods, such as MP2-R12, contain terms in the wave function that are linear in the inter-electronic distances r_{ij} (hence the name). Appearance of several types of two-body integrals is due to the use of the approximate resolution of the identity to reduce three- and four-body integrals to products of simpler integrals.
