How are water's material properties encoded within the structure of the water molecule? This
is pertinent to understanding Earth's living systems, its materials, its geochemistry and …

The way in which a three-dimensional network of water molecules accommodates an
excess proton is hard to discern from the broad vibrational spectra of dilute acids. The …

There is considerable disagreement over whether the gas/liquid surface of water is positive
due to the presence of surface-active hydrogen ions or negative due to the presence of …

Although messenger mediated spectroscopy is a widely-used technique to study gas phase
ionic species, effects of messengers themselves are not necessarily clear. In this study, we …

Size-selective infrared (IR) spectroscopy of gas phase water-containing clusters is
performed to probe microscopic natures of hydrogen-bonded water networks. Size-selective …

We study the hydration of protons in liquid water using terahertz time-domain spectroscopy
and polarization-resolved femtosecond midinfrared pump-probe spectroscopy. We observe …

Because H-bonding causes unique properties of water, structures of H-bonded water
networks are of fundamental interest. For molecular-level understanding of H-bonded …

Understanding the correlation between structure and reactivity of oxide surfaces is vital for
the rational design of catalytic materials. In this work, we demonstrate the exceptional …

Three different commonly used infrared photodissociation (IRPD) spectroscopy acquisition
and analysis methods are described, and results from these methods are compared using …

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 …
