An ion pair is defined to exist when a cation and an anion are close in space and share a common solvation shell; the energy associated with their electrostatic attraction is larger than the thermal energy (RT) available to separate them. The ions must also stay associated longer than the time required for Brownian motion to separate non-interacting species. Only strict electrostatic interactions should occur between the ions. No interactions other than the Coulombic attraction should formally exist upon the association of the charges, which existed prior to the interaction and remain unchanged in the interaction.
