Gibbs energy dissipated when a system that has undergone 'vertical' @[email protected] (i.e., @[email protected] obeying the @[email protected]) relaxes to the equilibrium state for its new charge distribution. Commonly the total reorganization energy (\(\lambda\)) is written as the sum of an inner contribution (\(\lambda_{\text{in}}\)) and an outer contribution (\(\lambda_{\text{out}}\)) attributed to nuclear reorganizations of the redox partners and their environment (solvent), respectively.
