Abstract

 Charge  transfer (CT) at  liquid/liquid  interfaces are described  theoretically depending on  the quantum theory .A model that derived used to calculate the rate constant  of transport at liquid/liquid  interfaces. The calculation of the rate constant of  charge  transfer depends on  the calculation of the reorganization energy, driving force ,and the coupling coefficient . Large reorganization energies  and large rate constant  for charge transfer ,indicate that the transitions involve more energy to happen . The system have large 𝐸0 (𝑒𝑉) refers that  type  of  liquid  is more reactive media than other liquid types with same donor. Driving force energy to drive the charge increases with the increase of absorption energy and decrease of in wave length. Height barrier at liquid/liquid interface that decreasing with decreasing the driving force energy and increasing the absorption energies  .Charge  transfer is so much small as a barrier of large values but in the low values of  barrier ,the transfer is most probable. The large height  barrier exclusion transfers across liquid/liquid system and the charger suffers from much resistant to transfer . However, this excluded transfer could be significantly large for high barrier and  small  concentrations .The theoretical  values of rate constant of charge transfer show a good agreement with some of the experimental studies
