    "abstract": "The dynamics and infrared absorption spectrum of the protonated water dimer\nare reported by full quantum simulation. Strong couplings between the\nspectroscopically active proton-transfer motion and low-frequency,\nlarge-amplitude torsional modes are clearly identified and their role in the\ncluster dynamics is explained. These couplings are responsible for the\ncharacteristic doublet-peak around 1000 cm-1, which was not understood and\nsubject of debate. This spectral feature is reproduced, assigned and explained.",
