Study of liquid-crystal phase transformation in KNO3 solution by Raman spectroscopy

Liquid-crystal phase transformation, metastable area around saturation point and precrystallization clusters in water-salt KNO3 solution are investigated by Raman spectroscopy. We presented the existence of a quite wide solution metastable area in case of the temperature change, and also line shifts and broadenings in the Raman spectra are related to the presence of cluster associations during liquid-crystal phase transformation.
