SpletThe Ritchie equation, derived in 1972, is another free-energy relationship:[5][6][7] where N + is the nucleophile dependent parameter and k0 the reaction rate constant for water. In this equation, a substrate-dependent parameter like s in the Swain–Scott equation is absent. The equation states that two SpletThe Swain Scott equation- Correlations for nucleophillic reactions.
