Quantum mechanical (QM) calculations are critical in quantitatively understanding the
relationship between the structure and physicochemical properties of various chemical …

The ease with which the pH is routinely determined for aqueous solutions masks the fact that
the cationic product of Arrhenius acid dissolution, the hydrated proton, or H+ (aq), is a …

The spectroscopic features of protonated water species in dilute acid solutions have been
long sought after for understanding the microscopic behavior of the proton in water with gas …

Many efforts undertaken to study the solvation process have led to general theories that may
describe mean properties, but are unable to provide a detailed understanding at the …

A mid-infrared oscillator FEL has been commissioned at the Fritz Haber Institute. The
accelerator consists of a thermionic gridded gun, a subharmonic buncher, and two S-band …

We review the role that gas-phase, size-selected protonated water clusters, H+ (H2O) n,
have played in unraveling the microscopic mechanics responsible for the spectroscopic …

Infrared spectroscopic study of neutral water clusters is crucial to understanding of the
hydrogen-bonding networks in liquid water and ice. Here we report infrared spectra of size …

The structure of the excess proton in liquid water has been the subject of lively debate on
both experimental and theoretical fronts for the last century. Fluctuations of the proton are …

The diffuse vibrational envelope displayed by water precludes direct observation of how
different hydrogen-bond topologies dictate the spectral response of individual hydroxy group …

Vibrational spectroscopy of the protonated water trimer provides a stringent constraint on the
details of the potential energy surface (PES) and vibrational dynamics governing excess …
