Photoinduced Electron Transfer Between Metalloporphyrin Complex Dihydroxy Antimony (V) Tetraphenylporphine and Halide in Acetonitrile Solution

Electron transfer (ET) through molecular frameworks is central to a wide range of chemical, physical , an biological processes. Atheoretical calculation investigation of (ET) between dihydroxy antimony (V) tetraphenylporphine cation [Sbv(TPP)(04)2] and halid CI ,Br,I is presented . These Calculations are is fiting on expermental studies Showing that the rate of Electron Transfer. The theoretical Calculation are based on a continuum theory. The transferring is treated quantum mechanically, and the solvent is represented as adielectric continuum. For electronically nonadiabatic E T , the rate expressions for (ET),Ket ,depend on the electronic Coupling matrix element ,HAb , the free energy change of the reaction AG0 , and the reorganization energy X
