It is frequently considered that valence-bond theory is not easily adapted to provide qualitative descriptions of molecular excited states. No doubt this is often true. However, for some simple systems, there exists an elementary valence-bond counterpart for each molecular orbital description of the excited state. To demonstrate this point, we shall give consideration here to a few types of electronic excitations.
