Description
Summary:Raman spectroscopy and the phonon confinement model (PCM) have been used to study the two ordered structures in liquid water, “structured hydrogen bonded water” and “nano-ice”, whose existence has recently been confirmed by a hyperspectral analysis of 140 temperature dependent Raman spectra (−23 to 45 °C). The PCM spectral simulation based on the ice Ih structure indicates that vibrations are limited within a short range of few molecules in “structured hydrogen bonded water”, while they extend to about a 2–4 nm range in “Nano-ice”.
