Electrochemical characterisation of ionic dynamics resulting from spin conversion of water isomers

英文摘要：

Para- and ortho- isomers of water have different chemical and physical properties. Excitations by magnetic field, laser emission or hydrodynamic cavitation are reported to change energetic levels and spin configurations of water molecules that in turn change macroscopically measurable properties of aqueous solutions. Similar scheme is also explored for dissolved molecular oxygen, where physical excitations form singlet oxygen with different spin configurations and generate a long chain of ionic and free-radical reactions. This work utilizes electrochemical impedance spectroscopy (EIS) to characterize ionic dynamics of proposed spin conversion methods applied to dissolving of carbon dioxide CO$_2$ and hydrogen peroxide H$_2$O$_2$ in pure water excited by fluctuating weak magnetic field in uT range. Measurement results demonstrate different ionic reactivities and surface tension effects triggered by excitations at 10$^{-8}$J/mL. The CO$_2$- and O$_2$-related reaction pathways are well distinguishable by EIS. Control experiments without CO$_2$/H$_2$O$_2$ input show no significant effects. Dynamics of electrochemical impedances and temperature of fluids indicates anomalous quasi-periodical fluctuations pointing to possible carbonate-induced cyclic reactions or cyclical spin conversion processes. This approach can underlay development of affordable sensors operating with spin conversion technologies.
