================
Integrals_Bielec
================

Here, all two-electron integrals (:math:`1/r_{12}`) are computed. As they have
4 indices and many are zero, they are stored in a map, as defined in
``Utils/map_module.f90``.  To fetch an AO integral, use the
``get_ao_bielec_integral(i,j,k,l,ao_integrals_map)`` function, and to fetch and
MO integral, use ``get_mo_bielec_integral(i,j,k,l,mo_integrals_map)`` or
``mo_bielec_integral(i,j,k,l)``.

The conventions are:

* For AO integrals : (ik|jl) = (11|22)
* For MO integrals : <ij|kl> = <12|12>
