<b>Chapter 9 </b>
<b>Exercise 1.</b> Determine the term symbols for the ground states of O2 and O2+
<i><b> </b></i>
<b>Exercise 2</b>. Determine the symmetry designation (g or u) for the term symbol of
the ground-‐state electron configuration of B2
<b>Exercise 3 </b>
Express the Hamiltonian operator for a hydrogen molecule in atomic units
<b>Exercise 4</b>
In this problem, we consider the heteronuclear diatomic molecule CO. The
ionization energies of an electron from the valance atomic orbitals on the carbon
atom and the oxygen atom are listed below:
Use these data to construct a molecular orbital energy level diagram for CO.
What are these symmetry designations of the molecular orbitals of CO. What is
the electron configuration of the ground state of CO? What is the bond order of
CO? Is CO paramagnetic or diamagnetic?
