Investigation of the single proton dynamics in light water and ice-Ih applying an external electrostatic field

DOI

Water, being dipolar, can be partly aligned by an electric field and this can be easily shown by the movement of a stream of water close to an electrostatic source. High field strengths (about 5E9 V/m) are required to reorient water in ice such that freezing is inhibited, with lower fields (about 1E5 V/m) encouraging ice formation in supercooled water by weakening the hydrogen bonding. Even a partial alignment of the water molecules with the electric field will cause pre-existing hydrogen bonding to become bent or broken. This experiment intends to be a first attempt to measure the microscopic dynamical effects induced at the level of the single atoms when an external physical perturbation modifies the structural and chemico-physical environment of the atoms themselves. We propose a ontinuation of a previous DINS measurement that failed because of technical problems wtth sample container
