Abstract
The conducted studies have shown that the best changes occur in water irradiated with PVIP light during 4 and 15 minutes as compared to the absorption spectra of a control specimen of tap water. Significant changes in the water structure occurred if water was irradiated with PVIP light from a 10 cm height above the water surface during 15 minutes. The most significant changes in the water structure have been observed if water was irradiated with PVIP light during 4 minutes and was concurrently saturated during the same time period with CO2 cooled to 0 °C. The data of the spectral analysis of water after the effect of electromagnetic radiation with a wavelength of 5,6 mm and frequency belonging to a 50-52 GHz range virtually coincide with those of the water irradiated with PVIP light, i.e., with a 4 and 15-minute exposure.
