The O-H stretching fundamental spectra of water clusters are well known from cold jet expansions, but their detection in the atmosphere remains elusive. Mild supersonic jet expansions of neat water vapor are used to detect trimers and tetramers with intermediate thermal excitation. Spectra close to the evaporative limit are obtained by interfering neighboring expansion fans in a multi slit nozzle experiment. They are interpreted in terms of ring opening in the water trimer, whereas the tetramer…

Temperature Dependence of Intramolecular Vibrational Bands in Small Water Clusters.
TLDR
It is found that NQE can be accounted for simply by subtracting a constant from the frequencies obtained from the velocity autocorrelation functions (VACF) of classical nuclear dynamics, resulting in unprecedented agreement with experiment mostly within <5 cm-1.
Infrared spectroscopy of warm and neutral phenol-water clusters.
TLDR
A remarkable shift to higher frequency of the phenolic OH stretch band was observed with elevation of temperature, suggesting deformation of the cluster from the most stable cyclic structure to the transient chain-type structure.
Local Mode Approach to OH Stretch Spectra of Benzene-(H2O)n Clusters, n = 2-7.
TLDR
Isomer-specific resonant ion-dip infrared spectra for benzene-water (Bz-(H2O)n) clusters with two to seven water molecules provide insight into benzene's effects on the three-dimensional hydrogen-bonded networks present in water hexamer and heptamer structures.
Probing the intermolecular coupled vibrations in a water cluster with inelastic electron tunneling spectroscopy.
TLDR
Using tip-enhanced inelastic electron tunneling spectroscopy (IETS) based on low-temperature scanning tunneling microscopy, the direct quantitative assessment of the intermolecular coupling constants of the OH-stretch vibrational bands of an isolated water tetramer adsorbed on a Au(111)-supported NaCl(001) bilayer film is reported.
Structure, spectroscopy, and dynamics of the phenol-(water)2 cluster at low and high temperatures.
TLDR
The temperature effect is described using ab initio molecular dynamics with a density functional and basis-set that provide a realistic description of OH⋯O vs. OH ⋯π HBing and from the dipole moment autocorrelation function, good description is obtained for both low- and high-T spectra.
Thermally Induced Hydrogen-Bond Rearrangements in Small Water Clusters and the Persistent Water Tetramer
TLDR
It is found that logarithmically small tails in the radial probability densities of (H2O)n clusters provide direct testimony for phase transitions, finding that both melting and vaporization proceed via a “monomer on a ring” conformer, exhibiting huge distance fluctuations at the vaporization temperatures (Tv).
Stepwise Internal Energy Change of Protonated Methanol Clusters By Using the Inert Gas Tagging.
TLDR
To explore an isomer population profile, stepwise changes of internal vibrational energy of a protonated hydrogen-bonded cluster are performed by inert gas tagging and the observed relative population follows its theoretically predicted temperature dependence.
Intermolecular energy scales based on aromatic ethers and alcohols
The interplay between London dispersion interactions and hydrogen bonding is investigated by the binding preference of molecular scale systems in the gas phase. These molecular complexes consist of…
Hydrogen bond network structures of protonated short-chain alcohol clusters.
TLDR
This work focuses on the structural study of protonated short-chain alcohol clusters, whose excess protons enable size-selective spectroscopy in combination with mass spectrometric techniques and their hydrogen bond network development is elucidated in detail.

TLDR
Comparison with infrared spectra provides direct experimental insights into the hydrogen bond-mediated excitonic OH oscillator coupling, which is responsible for ultrafast energy transfer between water molecules, usually suppressed by isotopic dilution in femtosecond experiments for the condensed phase.
