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.

Some aspects of the scope and limitations of derivative spectroscopy

TL;DR: In this paper, it is suggested that the practice of computing a least-squares fit of overlapping bands to a spectral profile be changed, because the minimisation achieved often produces a result involving excessive or negative absorbances: the spectral profile should be regarded as a boundary limit and any unaccounted absorbance then assessed as possible evidence for an additional band.

TL;DR: In this paper, a series of articles devoted to the theoretical calculation and physical interpretation of the band shapes in the infra-red and Raman spectra of H-bonded liquids on the basis of the fluctuation model of hydrogen bonding is presented.

Stimulated raman spectra from H2O, D2O, HDO, and solutions of NaClO4 in H2O and D2O
TL;DR: Stimulated Raman spectra were obtained from H2O and D2O mixtures using picosecond pulse excitation at 530.0 nm as discussed by the authors, and the stimulated emission peaks could be predicted from the spontaneous Raman contour shapes for the OD stretching vibrations, but exclusive stimulation of either hydrogen-bonded or of non-hydrogen-bunded components was observed for the OH stretching vibrations.

TL;DR: In this article, the contour shapes in the infra-red and Raman spectra of the 1 : 1 and 1 : 2 type complexes of ordinary and heavy water with two organic bases, dioxane and dimethyl sulphoxide, were calculated by means of a computer.
