Abstract:
The high polarizability of halide anions affects, in aqueous solutions, many phenomena ranging from hydrogen bond dynamics to water interfaces' structure. In this Letter dipolar interactions of halides in water are investigated through Car-Parrinello Molecular Dynamics simulations. Contrary to previous studies, a different polarization of first and second hydration shell water molecules is found. The analysis hints that existing classical polarizable force fields lack a description of short-range interactions which causes an overestimation of polarization effects.

Alkyl Halides
Alkyl halides are halogen-substituted alkanes wherein one or more hydrogen atoms of an alkane is replaced by a halogen atom such as fluorine, chlorine, bromine, or iodine. The carbon atom in an alkyl halide is bonded to the halogen atom, which is sp3-hybridized and exhibits a tetrahedral shape.
Unlike alkyl halides, compounds in which a halogen atom is bonded to an sp2 -hybridized carbon atom of a carbon-carbon double bond (C=C) are called vinyl halides. Whereas aryl...

Aqueous Solutions and Heats of Hydration
When ionic compounds dissolve in water, the ions in the solid separate and disperse uniformly throughout the solution because water molecules surround and solvate the ions, reducing the strong electrostatic forces between them. This process...
