driving force (for electron transfer)

https://doi.org/10.1351/goldbook.DT07363
Term widely used to indicate the negative of the standard Gibbs energy change for outer-sphere electron transfer (\(\Delta _{\text{ET}}G^{\,\unicode{x26ac}}\)).
Note:
For photo-induced processes, this quantity can often be estimated from independently determined properties of the donor and acceptor species involved using the equation for the calculation of the @GT07388@.
