“…Despite the fact that the influence of inorganic as well as organic solutes on the liquid water structure has been intensively investigated by various methods, including X-ray, NMR and IR/Raman spectroscopy, some aspects of the phenomenon still remain uncertain [1][2][3][4][5][6][7][8]. In this connection studying the Raman spectra of aqueous solutions is considered to be rather informative owing to high sensitivity of the O-H stretching band (ν~2800-3800 cm -1 ) to the local environment of water molecules.…”

At the same time the role of metal ions in water bonding was not adequately investigated and the similar sequences for single-or doubly charged cations were difficult to obtain exactly because of their effects insignificance [1,4,8].…”

Absrtact.The Raman spectra in the region of the O-H stretching vibration band are used to investigate the effect of lanthanide (III) ions on liquid water structure in concentrated aqueous solutions of CeCl 3 and GdCl 3 (C~0.5‚3 M). The differential spectra, derived from the consequent Raman spectra, have reflected the substantial discrepancy between the spectra of lanthanide (III) salt solutions and pure water as well as the spectra of standard LiCl (C~1.5‚9M) solutions. The new sharp bands (ν max ~ 3180‚3190 cm -1 ) and (ν max~3 360 cm -1 ), observed in the differential spectra, are assumed to two types of aqua-ions: Ln 3+

Raman spectroscopy provides an efficient method for non-contact determination of liquid water temperature with high spatial resolution. It can be also used for remote in situ determination of subsurface water temperature. The method is based on temperature-dependent changes of the molecular O-H stretching band in the Raman spectra of liquid water. These in turn are attributed to a decrease in intermolecular hydrogen-bonding interactions with increase in temperature. Here, the results of an experimental study employing three different approaches in the determination of temperature from recorded O-H stretching band in the Raman spectra of liquid and supercooled water are presented and discussed. The first two methods are based on deconvolution of the spectral band into Gaussian components whose intensities and associated specific spectral markers are temperature dependent, and the third approach is based on Raman difference spectroscopy (RDS). The presented measurements were conducted on distilled and deionized supercooled and liquid water in the temperature range between −12.5 and +32.5• C. The results are compared in terms of linearity of response, sensitivity and accuracy. It is shown that the method based on RDS even in the supercooled temperature range provides better accuracy (the standard deviation from the true temperature is ±0.4 K) and linearity in temperature determination than more complicated methods based on Gaussian deconvolution of the O-H stretching band.

A semiautomated method combining intensity normalization with effective elimination of the solvent signal and non-Raman background is presented for Raman spectra of biochemical and biological analytes in aqueous solutions. The method is particularly suitable for rapid and effortless preprocessing of extensive datasets taken as a function of gradually varied physicochemical parameters, e.g. analyte and/or ligand concentration, temperature, pH, pressure, ionic strength, time, etc. For intensity normalization, the strong Raman OH stretching band of water in the range of 2700-3900 cm −1 recorded together with the analyte spectrum in the fingerprint region below 1800 cm −1 is employed as internal intensity standard. Concomitant dependences of the solvent Raman spectra are taken into account and, in some cases, turned into advantage. Once the Raman spectra of the solvent are acquired for a particular range of the parameter varied, solvent contribution can be subtracted correctly from any analyte spectrum taken within this range. The procedure presented can be efficiently applied only for the analytes having their own Raman signal in the range of OH stretching vibrations much weaker than that of the solvent. However, this is the case for a great number of biochemical and biological samples. Accuracy, reliability and robustness of the method were tested under the conditions of spontaneous Raman, resonance Raman and surface-enhanced Raman scattering. Serviceability of the method is demonstrated by several real-world examples.
