THE EFFECT OF OXIDATION NUMBER ON REFRACTIVE INDEX BASED ON STRING THEORY

In this work we used ordinary second Newton Law for electrons affected by electric field in a viscous medium; one finds real and imaginary electric susceptibility then the refractive index; susceptibility and conductivity are related to each other. By considering the photon as string that is emitted or absorbed due to electronic transition for hydrogen like atom, the refractive index is shown to be inversely proportional to the atomic number. This relation conforms to the experiments done on Fe, Co, Ni, Cu and Cr oxides.
