Terahertz dynamics of nanoconfined water molecules

Original language description

We performed spectroscopic studies of watercontaining beryl crystals. At terahertz frequencies, we observed a strongly temperature-dependent spectral feature, corresponding to a collective excitation caused by dipole-dipole interactions between separate H2O molecules. We associate the excitation with a soft mode signaling an incipient ferroelectric state within the water molecular subsystem. Single-particle excitations of nanocaged H2O molecules are also observed at terahertz and infrared frequencies using DFT analysis, their origin is assigned to translational and librational vibrational states.n
