Perturbation calculation from the charge-transfer spectrum data of intervalence site-transfer D.C. conductivity in Prussian Blue

Abstract

Observed parameters from the charge-transfer spectrum of a thin film of Prussian Blue are employed in the Hush perturbation treatment yielding, from the tunnelling matrix and activation energy of thermal electron-transfer, an electron-transfer frequency which is equated with the so-called hopping frequency in conductivity, to obtain a calculated conductivity of 0·43 × 10^–7Ω^–1 cm^–1; cf. an observed conductivity, for the sample, of 1·7 × 10^–7.
