The group theoretical analysis of the electronic structure of l,4-dihydro-l,4-bis (dicyanoinethylene)triptycene leads to an interesting but rarely documented notion, "charge transfer transition for symmetry forbidden charge transfer interaction" , which was supported by the substituent effects on the charge transfer band shifts. The substituent effects on the charge transfer band shifts were al...

Tunneling spectroscopy has been used to detect the photoexcitation of charge carriers in the wide band-gap semiconductors, ZnO and cubic SiC. Because the process is energy sensitive, valence-toconduction hand or defect charge transfer transitions may be selectively excited and detected with the scanning tunneling microscope. Two types of transitions were detected which change the tunneling resp...

Using first-principles calculations, we study the electronic structures of Pt/HfO2 interface in the presence of oxygen vacancy. The energetics and charge transfer are examined when the oxygen vacancy is at various distances from the interface. It is found that the oxygen vacancy is strongly attracted to the interface and the charge transfer decreases monotonically as the vacancy moves away from...

fac-[Re(CO)3(dppz)] complexes of amido ligands generated in situ under basic conditions display an intense (ε = 16460 L mol-1 cm-1) absorption band between 500-700 nm which are assigned to an n(amido,RNH-) → π* (dppz) inter-ligand charge transfer band offering an extraordinarily low energy charge separating absorption with potential for imaging and energy application.
