An optical cell for Raman spectroscopic studies of supercritical fluids and its application to the study of water to 500°C and 2000 bar
TL;DR: In this article, a high-temperature, high-pressure optical cell has been developed for the study of aqueous solutions by Raman spectroscopy, which has a sample volume of < 1 ml and utilizes diamond or sapphire windows set at 90° to one-another.

TL;DR: In this paper, the effect of hydrogen carbonate (HCO 3 − ) and cations (Na +, K + ) solvated in water were revisited according to high spectrally resolved Raman measurements.
Journal ArticleDOI
The role of water in biological systems
TL;DR: A general model of the liquid water structure consistent with its physical, chemical, structural, and also biological properties has not been described in the literature so far as mentioned in this paper, and therefore, different structure models of liquid water have been taken into account in relation to its OH stretching Raman modes.

Raman spectrum of liquid water and Luck's two state model
M. C. Shivaglal,Surjit Singh +1 more
TL;DR: In this paper, it was suggested that the Raman spectrum for water can be explained on the basis of the presence of free and hydrogen-bonded OH bonds.

Some Roles of Water in Biological Systems
TL;DR: The role of water in life processes is very important but very complex too depending on the structure of liquid water and on the particular physical and chemical properties of this hydride, and also on the interactions between water and biological molecules.

The fluctuation hypothesis of hydrogen bonding: III. The calculation of the vibrational spectra of water complexes of the type 1-1
Yu. Ya. Efimov,Yu. I. Naberukhin +1 more
TL;DR: In this article, the authors derived the band shape in the infra-red and Raman spectra of stretching vibrations of H2O molecules with only one OH group involved in H-bonding (so-called complexes of the type 1-1 [1]).

TL;DR: On the basis of a fluctuation model of hydrogen bonding which takes into account the nonequivalence of H-bonds due to fluctuations of local environments in liquids, a mathematical formalism is developed in this paper.

The characterization of infrared absorption band shapes. II. Experimental studies
TL;DR: Inverse polynomials of the type y = a (1 + bx 2 + cx 3 + dx 4 ) −1 prove to be very convenient and, unlike truncated moments and log/log plots of band shapes, do not require the location of an accurate experimental baseline.
