8. Consider the molecule H2+ 3 , in which the three protons are arranged linearly. Let proton A be on the left, proton B be in the middle and proton C be on the right, with the distance between proton A and B the same as the distance between proton B and C. Here we will use the LCAO approach to construct the three lowest energy molecular orbitals. a. Write down the electronic Hamiltonian Hˆ elec. You may use the notation Kˆ e for the kinetic energy, but you must write down explicit forms for Ven and Vee.
