Role of hydrogen bonds in molecular relaxation during electron transport processes in biological systems
Computer Research and Modeling, 2009, v. 1, no. 3, pp. 297-320Views (last year): 6. Citations: 3 (RSCI).In molecular systems with hydrogen bonds the mechanism of proton relaxation can take place. It is caused by redistribution of protons between two steady positions in double walls potential along the line of the hydrogen bond. This redistribution occurs at change of parameters of the double walls potential of the hydrogen bond which is caused by change of an electronic state of molecular system. The relaxation process is carried out due to a tunnel transfer of protons along the line of bonds. It is shown, that relaxation process can define temperature dependence of power parameters (either of the free energy differences ΔG or of the reorganization energy λ) of charge recombination P+Q-A from RC of Rhodobacter sphaeroides.
