Extended Electron States in Proteins //J. Mol. El., 1990, v.6, p.155-166
A new approach to the problem of electron states in the protein molecule is described. A "dielectric cavity" model for a protein globule is used as a basis to consider the extended states which are mostly formed by the polarization field of the protein macromolecule. In a protein solution the size of such a state can be compared with the size of the macromolecule. The share of the extended states in the biomolecular processes of charge transfer is discussed. Electron energies of the ground and the first excited self-consistent states are calculated. Typical values of the predicted energies of absorbtion bands and luminescence are found to be Ca 1000 nm for the ground state absorbtion band and Ca 2000 nm for the excited state luminescence. Various ways of experimentally observing such states are discussed.
