We demonstrate moleculelike modes by analyzing the angular correlations
of triply excited states in a model three-electron problem.
The nodal patterns of the internal functions manifest the
normal modes of a quadriatomic molecule.
We also show the relative energy levels of the triply excited
states exhibit a rotor structure.
