The influence of electromagnetic radiation of optical and millimetre-wave bands on the viscosity and the coefficient of surface tension of aqueous solution of NADH is studied experimentally. Measurements of solution parameters are carried out using the measurement and analysis of spectra of capillary waves on the free surface. As revealed, under the influence of electromagnetic radiation with the frequency of 60 GHz and power of 10?4 W/cm2 during 20 min, viscosity and surface tension of water bidistillate are increased. The same impact on the aqueous solution of NADH decreases the values of viscosity and surface tension. The magnitudes of changes in viscosity and surface tension of solutions depend on the spatial frequencies of capillary waves. As concluded, the changes in conformation of molecules of NADH in aqueous solution under the influence of the radiation of weak intensity could take place. For the case of 3–5% NADH concentration, change in solution viscosity reaches 10–15%.
