According to Mulliken overlap populations calculated for Ni -CO and C-O bond, it is found that the strong co-valent bonding of Ni to Ti3+ does not drastically suppress the ability of Ni atoms to adsorb CO, and the electronic transfer between Ti3+ and Ni atom does not lead to any increase in activation of adsorbed CO.
Thus, it is suggested that the electronic factor which means strong bonding of Ni to Ti3+ and electronic transfer between Ni and Ti3+ is not the main reason causing the strong metal support interaction (SMSI).
The electronic transfer coefficient (a), the number of electrons (n) and protons (m) involved in the electrode reaction of EBT and Ga(Ⅲ)-EBT were estimated to be 0.38 and 0.58 for a, 2 for n and m,resp ctively.
Proton transfer along the hydrogen bond for the transmission of biological elements, such transfers were considered in the biological system is the process of energy transmission and electronic transfer of the same importance.
From the measurements of absorption,fluorescence and fluorescence quenching spectra and the photo acid generation it was found that the photosensitive acid generation had the nature of a photo electronic transfer process.
It is deduced that F- and Cl- have entered into on the surface of the cathod and formed a bridged complex with reduced chromium dichromate, [CrIII-X--CrIII], in which electron transition was easily carried out.
In the ethylene glycol solvent the CIDEP effects of the naphthosemiquinone radical and ethylene glycol ketyl radical after irradiation at 308nm were observed due to triplet mechanism (TM). In the TX - 100 micelle solution, the signals of the spin polarization of the naphthoquinone anion were observed, which was attributed to the electron transition between the polarized triplet of the naphthoquinone and TX - 100 micelle.
Photoinduced intramolecular electron transfer process from C60 moiety to carbazole moiety has been studied by nanosecond laser flash photolysis.
The electron transfer coefficient and apparent reaction rate constant were determined to be 0.861 and 1.27 s-1.
This causes a significant increase in the efficiency of further electron transfer to the primary quinone acceptor as compared to a system with two absolutely symmetric electron transfer branches.
Reactions of electron transfer from the primary to secondary quinone acceptors and from the multiheme cytochrome c subunit to photoactive bacteriochlorophyll dimer were used as probes of electron transport efficiency.
The thermoinduced transition of the acceptor complex to the conformational state facilitating electron transfer to the secondary quinone acceptor was studied.
Although the two electron-transfer branches in the reaction centers (RC) of purple bacteria are virtually symmetric, it is well known that only one of them is functionally active (the A-branch).
The results indicate that residues Arg425 and Arg426 are involved in the formation of a heme-binding center and electrostatic interaction of cytochrome P450scc with its physiological electron-transfer partner, adrenodoxin.
The kinetics of oxidation of 4-hydroxybiphenyl (4-HBP) catalyzed by laccase from Polyporus pinsitus was studied in the presence of methyl syringate (MS), which acts as an electron-transfer mediator.

Formation Enthalpy of Exciplexes with Partial Charge Transfer as a Function of the Electron-Transfer Driving Force
The temperature dependence and rate of the Z1-center formation is in agreement with the corresponding results on FA-center formation, demonstrating that Z1-centers are formed as the consequence of an ionic process and not a mere electronic transfer.
This work indicates that the excitation to the first and second singlet induces an electronic transfer from the heteroatom in the case of ortho and para derivatives; for meta compounds, the same phenomenon occurs for the four first singlets.
Electronic transfer processes studied at different time scales by selective resonant core hole excitation of adsorbed molecules
Direct electronic transfer of PACS images reduces the number of steps involved in creating publication-quality images as well as providing the means to produce high-quality radiographic images in a digital environment.
