Query: The local structure of electrically stressed liquid water and
  implications for modelling of dielectric relaxation   In a floating water bridge the total radiation scattering of water stressed
by a moderately strong electric field (1mV/nm) was compared to water without an
applied electric field using X-ray and small angle neutron scattering.
Structure refinement was carried out using the EPSR method and the TIP4P/2005
water model. These results did not reveal a significant difference in the local
static structure of water however analysis of the simulation indicated that the
modeled local potential energy surface reveals a departure between electrically
stressed and unstressed water. The observed differences show that the local
environment is changed by the applied electric field although weak relative to
the intermolecular coulombic field. When discussing the results we show that
the current methods used to simulate the pair potentials are still insufficient
to treat such non-equilibrium systems and further simulation techniques have to
be developed to properly reconstruct the microscopic dielectric relaxation
process.
