✦ Synopsis


It is found that distilled water possesses weak luminescence in the near UV and visible regions of the spectrum. The excitation spectrum is complex and has two main maxima, at 260 and 310 nm. The corresponding emission spectra apart from narrow lines due to Raman scattering are represented by wide lines at 360 and 410 nm and are determined by the inherent properties of water. The intensity of luminescence depends on the time of holding of a sample in a closed vessel and on addition of trace amounts of both luminescent and non-luminescent substances. The observed phenomenon can not he reduced to the luminescence of admixtures in water, but is a result of unique properties of water, its structure and polymorphism. Relative intensities of the described bands of emission are greatly sensitive to weak fields of electromagnetic nature. The phenomena observed lead to the conclusion that water and aqueous solutions should be regarded as continuous polymorphous serf-organizing systems.
