Abstract: “Physical properties of ordered water in the vicinity of various hydrophilic surfaces are different in many areas, such as viscosity, charge, movement and characteristics of molecules in its composition. One of these diversities was shown in the experiments including UV-Vis absorption spectra, where was shown significant absorbance of water in this area at the wavelength of 270 nm. Mathematical model for examined absorption spectra based on the appropriate differential equation and conditions is formulated and presented in this paper. Derived model considerably corresponds to fitted normal (Gaussian) function for absorption spectra.”
