摘要：A detailed investigation of the applicability of the vibronically coupled electron tunneling theory in biomolecules can be made by a quantitative study of a weak charge-transfer optical absorption band that has been predicted by this theory. The measurement of the position, width, and molar extinction coefficient of this band is examined in the bound model system cytochrome c-Fe(CN)6 at room temperature and demonstrates that the theory is quantitatively applicable in this system. The size of the parameters measured is typical of those relevant for biological electron transfers. The comparisons lend credibility to the generality of vibronically coupled electron theory in biomolecules and its short transfer distances.
