Homework Help: Diatomic Hydrogen Molecule

  1. Nov 16, 2017 #1
    1. The problem statement, all variables and given/known data
    Consider an ##H_2## molecule where the protons are separated by a wide
    distance R and both are located on the z-axis. Ignoring the spin degrees
    of freedom and treating the dipole-dipole interaction as a perturbation,
    use perturbation theory to estimate an upper limit for the ground state
    energy of this molecule.

    2. Relevant equations

    3. The attempt at a solution
    What I think is that since hydrogen molecule has 0 dipole moment there should be no perturbation to calculate.

    The problem is asking you about the interaction between the two atoms that make up the molecule: how does one atom affect the other through a dipole-dipole interaction?
