A molecular dynamics simulation study of hydrogen bonding in aqueous ionic solutions

A series of molecular dynamics (MD) simulations have been carried out to study hydrogen bonding in aqueous ionic solutions at ambient conditions. Alkali metal and halides with different sizes have been considered. A separate study of the hydrogen bond (HB) populations in the first and second hydration shells has been performed and characteristic lifetimes of the hydrogen bonds have been determined in each case. The influence of ion size and charge is discussed.
