Low-energy excitations of a single water molecule are studied when confined within a nano-size cavity formed by the ionic crystal lattice. Optical spectra are measured of manganese doped beryl single crystal Mn:Be3Al2Si6O18, that contains water molecules individually isolated in 0.51 nm diameter voids within the crystal lattice. Two types of orientation are distinguished: water-I molecules have their dipole moments aligned perpendicular to the c axis and dipole moments of water-II molecules are…

Vibrational states of nano-confined water molecules in beryl investigated by first-principles calculations and optical experiments.
TLDR
Using quantum mechanical calculations within density functional theory, this work provides a comprehensive analysis of infrared-active excitation of water molecules confined in nanocages of a beryl crystal lattice and elucidate the applicability and efficiency of a combined experimental and computational approach.
Dielectric ordering of water molecules arranged in a dipolar lattice
TLDR
Measurements of the temperature-dependent dielectric permittivity, pyrocurrent, electric polarization and specific heat that indicate an order-disorder ferroelectric phase transition at T0 ≈ 3 K in the water dipolar lattice are presented.
Infrared spectroscopy of an endohedral water in fullerene.
TLDR
An infrared absorption spectroscopy study of the endohedral water molecule in a solid mixture of H2O@C60 and C60 was carried out at liquid helium temperature and the finite amplitudes of the pure v1 and v2 vibrational transitions are consistent with the interaction of the water molecule dipole moment with a lattice-induced electric field.
Quantum behavior of water nano-confined in beryl.
TLDR
The proton mean kinetic energy, Ke(H), of water confined in nanocavities of beryl at 5 K was obtained by simulating the partial vibrational density of states from density functional theory based first-principles calculations, in remarkable agreement with the 5 K deep inelastic neutron scattering measured value.
Broadband spectroscopy of H2O molecule confined in nano-cages of crystal lattice: Low-energy dynamics and incipient ferroelectric behavior
Broadband (1 Hz to 100 THz) dielectric response of water-containing beryl crystals was measured at temperatures from 300 K down to 0.3 K. The low-energy dynamics of H2O molecules confined within
Effect of fine-tuning pore structures on the dynamics of confined water.
TLDR
It is concluded that very small differences in the size and structure of the pores and the orientation of theWater molecule in these minerals result in changes in the potential of the water protons and drasticChanges in the confined water dynamics.
Terahertz dynamics of nanoconfined water molecules
We performed spectroscopic studies of water-containing beryl crystals. At terahertz frequencies, we observed a strongly temperature-dependent spectral feature, corresponding to a collective
Atomic resolution imaging of beryl: an investigation of the nano‐channel occupation
TLDR
The first experiments using atomic resolution scanning transmission electron microscope imaging (STEM) to investigate the channel occupation in beryl are presented and it is suggested that some or all of the atoms that are visible in the channels are Fe ions.
Rotational and Vibrational Excitations of a Single Water Molecule by Inelastic Electron Tunneling Spectroscopy.
TLDR
The results demonstrate a potential method to measure the dynamic behavior of a single molecule confined in a tunneling junction, where the molecule-substrate interaction can be purposely tuned.

Water conduction through the hydrophobic channel of a carbon nanotube
TLDR
Observations suggest that carbon nanotubes, with their rigid nonpolar structures, might be exploited as unique molecular channels for water and protons, with the channel occupancy and conductivity tunable by changes in the local channel polarity and solvent conditions.
Quantum Behavior of Water Molecules Confined to Nanocavities in Gemstones.
TLDR
In the present case of well-defined and highly symmetric nanocavities, the observed fine structure can be explained by macroscopic tunneling of the H2O molecules within a six-fold potential caused by the interaction of the molecule with the cavity walls.
Water-filled single-wall carbon nanotubes as molecular nanovalves.
TLDR
It is found that the resistivity of water-SWNTs exhibits a significant increase in gas atmospheres below a critical temperature Tc, at which a particular type of atmospheric gas molecule enters the SWNTs in an on-off fashion.

TLDR
The dynamic properties of water in beryl are investigated, finding that vibrations parallel to the c-axis channels are significantly more hindered than those perpendicular to the channels, and the resolution of the apparent contradiction between the inelastic neutron and dielectric spectroscopic results remains uncertain.
