(a) Distance dependence of strength of hydrogen bond for different cations when cation is attached to water donating hydrogen in HB. (no ion - red solid line, Li⁺ - green long dashed line, Na⁺ - blue dashed line, K⁺ - purple dotted line, Rb⁺ - lite blue long dashed dotted line, Cs⁺ - yellow dashed dotted line ) (b) Distance dependence of strength of hydrogen bond for different anions when anion is attached to water accepting hydrogen in HB. (no ion - red solid line, F⁻ - green long dashed line, Cl⁻ - blue dashed line, Br⁻ - purple dotted line, I⁺ - lite blue long dashed dotted line) Distance is in Å, energy in kcal mol⁻¹.
