Abstract
A method based on the rotational depolarization of fluorescence of dye molecules acting as luminescent sonds is proposed to study the temperature changes in the structure of water. A visible discrepancy of the experimental points from the linear Perrin formula was found for erythrosine B in water. From the emission anisotropy and the mean fluorescence lifetime, the effective Volume V of erythrosine B in water was determined. It was shown that the temperature changes in the effective volume can be associated with those in the water structure.
