Abstract:
The supramolecular organization of liquid water is discussed in connection with both the spectral profile of the OH stretching Raman signal measured in pure water and the distribution of tetrahedral order computed by molecular dynamics simulations. Both curves show common features and a similar temperature dependence never pointed out before. Energetic information extracted from the Raman profiles using a recently proposed integration method is also discussed. Overall results confirm that thermally induced structural variations of water in the interval of temperature ranging from 10 to 75 degrees C involve a change of the local tetrahedral order associated with a redistribution energy of 1.6-1.7 kcal/mol.

Raman Spectroscopy Instrumentation: Overview
The monochromatic laser source, typically using visible or near-infrared radiation, generates a highly focused beam of light. This light interacts with the molecules of the sample, scattering some of the light. Liquid and gaseous samples are usually tested in ordinary glass capillaries, while solids can be analyzed as powders packed in capillaries or as potassium...
