# A Deriving total energy in a Hydrogen molecule

I am looking for litterature that derives mathematically the total energy in a $H_2$ molecule by using quantum physics. Anyone knows a book they can recommend. I have seen derivations for helium atom for example:

I need something similar for the hydrogen atom. Anyone? Cheers!

The hydrogen molecule is a 4 particle system. When I was a senior in QM, I wrote a program that solved for the energy H2 as a function of inter-nuclear separation. I used the Hartree Fock method to solve for the energy. There are a lot of integrals that must be evaluated, so I wrote a numerical routine to solve for the integrals.
