Marcus Theory - The Macroscopic System: Two Conducting Spheres
3) Marcus separates the inner sphere (reactant + tightly bound solvent molecules, in complexes + ligands) and the outer sphere (free solvent ) (4) In ... The outer sphere energy is often much larger than the inner sphere contribution because of the far reaching electrostatic forces (compare the Debye-Hüc ... is substituted by two macroscopic conducting spheres at a defined distance carrying specified charges ...
Marcus Theory - Inner Sphere Electron Transfer
... In the outer sphere model the donor or acceptor and the tightly bound solvation shells or the complex’ ligands were considered to form rigid structures which do not change in the course of electron transfer ... However, the distances in the inner sphere are dependent on the charge of donor and acceptor, e.g ... In this inner sphere case the Arrhenius concept holds, the transition state of definite geometric structure is reached along a geometrical reaction coordinate determined by nuclear motions ...

Famous quotes containing the words sphere and/or outer:

    If today there is a proper American “sphere of influence” it is this fragile sphere called earth upon which all men live and share a common fate—a sphere where our influence must be for peace and justice.
    Hubert H. Humphrey (1911–1978)

    Self-alienation is the source of all degradation as well as, on the contrary, the basis of all true elevation. The first step will be a look inward, an isolating contemplation of our self. Whoever remains standing here proceeds only halfway. The second step must be an active look outward, an autonomous, determined observation of the outer world.
    Novalis [Friedrich Von Hardenberg] (1772–1801)
