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.

Giuseppe Pezzotti,Giuseppe Pezzotti,Leonardo Puppulin,Angelo La Rosa,Angelo La Rosa,Marco Boffelli,Wenliang Zhu,Bryan J. McEntire,Shigekuni Hosogi,Takashi Nakahari,Yoshinori Marunaka +10 more
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.

Raman Spectral Studies of HDO in H2O
TL;DR: In this article, a 6.2M solution of D2O in H2O was analyzed by means of a specialpurpose analog computer, and two Gaussian components near 2510−2540 and 2630−2660 cm−1 were found to provide adequate fits of the contours in the temperature range involved, although some indication of a third weak Gaussian Raman component was found.

III. The effect of band width and band shape on resolution enhancement by derivative spectroscopy
W.F. Maddams,M.J. Southon +1 more
TL;DR: In this article, the effect of band width on the resolution of pairs of overlapping peaks, using second and fourth derivative spectra, and hence on the specificity of such derivative functions for peak finding, has been examined.

W.F. Maddams,W.L. Mead +1 more
TL;DR: In this paper, the performance of the Butler and Hopkins and the Savitzky and Golay methods for obtaining derivative spectra has been examined by calculating second and fourth derivatives of the synthetic peak consisting of the sum of two Lorentzian profiles of equal height and half width separated by their semi half width.
