Abstract
Experimental infrared multiple-photon dissociation (IRMPD) spectra recorded for a series of deprotonated dicarboxylic acids, HO2 (CH2 )n CO 2 - (n=2-4), are interpreted using a variety of computational methods. The broad bands centered near 1600 cm-1 can be reproduced neither by static vibrational calculations based on quantum chemistry nor by a dynamical description of individual structures using the many-body polarizable AMOEBA force field, strongly suggesting that these molecules experience dynamical proton sharing between the two carboxylic ends. To confirm this assumption, AMOEBA was combined with a two-state empirical valence-bond (EVB) model to allow for proton transfer in classical molecular dynamics simulations. Upon suitable parametrization based on ab initio reference data, the EVB-AMOEBA model satisfactorily reproduces the experimental infrared spectra, and the finite temperature dynamics reveals a significant amount of proton sharing in such systems.

Abstract
Measurement of velocity distributions of evaporated water monomers from small mass- and energy-selected protonated water clusters allows probing the extent of thermalization after excitation of these ultimately small nanodroplets. Electronic excitation of a molecule in the cluster is here induced by a single collision with an argon atom in the keV energy range. The measured velocity distributions of the departing neutral molecules exhibit bimodal shapes with a lower-velocity part consistent with a complete redistribution of the deposited energy in the entire cluster and a higher-velocity contribution corresponding to evaporation before complete energy redistribution. Statistical molecular dynamics calculations reproduce the bimodal shape of the velocity distributions by assuming an initial spreading of the excitation energy among all modes, thereby reproducing the lower velocity contribution of the distribution. By contrast, assuming the deposited energy to be initially localized among the modes of a single molecule leads to calculated distributions with two components whose shape is in accordance with the experimental results. The characteristics and the relative abundance of these two contributions in the velocity distributions obtained are presented and discussed as a function of the number of molecules (n = 2-10) in the ionized nanodroplet H+(H2O) n .

Abstract
The velocity of a molecule evaporated from a mass-selected protonated water nanodroplet is measured by velocity map imaging in combination with a recently developed mass spectrometry technique. The measured velocity distributions allow probing statistical energy redistribution in ultimately small water nanodroplets after ultrafast electronic excitation. As the droplet size increases, the velocity distribution rapidly approaches the behavior expected for macroscopic droplets. However, a distinct high-velocity contribution provides evidence of molecular evaporation before complete energy redistribution, corresponding to non-ergodic events.
