    "abstract": "When a laser pulse impinges on a molecule which is invariant under certain\nsymmetry operations selection rules for harmonic generation (HG) arise. In\nother words: symmetry controls which channels are open for the deposition and\nemission of laser energy---with the possible application of filtering or\namplification. We review the derivation of HG selection rules and study\nnumerically the interaction of laser pulses with an effectively one-dimensional\nring-shaped model molecule. The harmonic yields obtained from that model and\ntheir dependence on laser frequency and intensity are discussed. In a real\nexperiment obvious candidates for such molecules are benzene, other aromatic\ncompounds, or even nanotubes.",
