Abstract
A nonmonotonic bimodal dependence of elastic, Rayleigh scattering on the potassium phenosan concentration in an aqueous solution has been revealed. A similar dependence has been found, for the first time, for scattering amplitude fluctuations. The observed correlation is indicative of structural transitions in hydration shells of potassium phenosan, which are responsible for the increase and scatter of their size comparable with the wavelength (527 nm) of a laser spectrometer.
