title: Self-trapped vibrational states in synthetic beta-sheet helices.
abstract: Femtosecond vibrational pump-probe spectroscopy on beta-helical polyisocyanopeptides reveals vibrational self-trapping in the well-defined hydrogen-bonded side groups that is absent when non-hydrogen bonded monomers are mixed in.
