The dielectric properties response of aqueous LiOH solution at the microwave frequency

In this paper, we investigate the dielectric properties of aqueous LiOH solution over frequency range 20 MHz similar to 20GHz. The system behavior is well described according to four Cole-Cole (CC) terms whose evolution with composition is analyzed. Applying the extended Froehlich theory, we reveal the dual nature of water-ion and water-dipole interaction and propose an overview of the effects that water-ion interaction plays a dominating role in the aqueous LiOH solution system. With the theoretical framework 3D trajectory model, we find only about one H-bonded water cluster relaxes during the cutoff relaxation time interval 8.9 ps. The decay of the effective number of water molecules bound to the ions with its concentration, and Li+ perturb the water structure beyond the first hydration shell which is confirmed in the aqueous LiOH solution system.
