    1. The code to download, is offered as it is, for research or teaching purposes, without any warranty. The two versions that can be downloaded, are based on a CCSD(T) calculation for the quintet state and a splitting-difference method within the CAS-PT2 or MRCI approaches, for the singlet and triplet states as indicated in Ref. [1,2]. To download routines, 1) accept download conditions, and 2) write down your e-mail and compulsory data. The code consist of a small main program that allows us to compute the potential energies for several values of R, and/or angles together with the subroutines themselves that could be added to other codes.
