Abstract :
We have investigated dielectric relaxation in aqueous ionic solutions by terahertz time-domain spectroscopy to elucidate the ionic hydration effect on the structure of water. Our finding suggests the dissolved ion induces the “structure breaking effect” which weakens the hydrogen bonding of water beyond the ion hydration shell.
