Absorption lines in transition metal complexes

Femtosecond absorption spectroscopy of transition metal charge-transfer complexes.

Our research is concerned with the application of femtosecond time-resolved absorption techniques to the study of the photophysics of transition metal complexes. The focus is to understand the events that characterize the process of excited-state evolution from the time a photon is absorbed by a molecule to the formation of the lowest-energy excited state of the system. This Account describes o...

Electronic (Absorption) Spectra of 3d Transition Metal Complexes

Transition Metal Imido Complexes

A wide range of transition metal imido (TMI) complexes is studied using ab initio molecular orbital (MO) calculations. The main computational point of interest is the further testing of effective core potentials (ECPs) and valence basis sets to allow for the accurate calculation of properties for reasonably sized transition metal complexes. On the chemical side, several results from the study a...

Metal Hydrides: Transition Metal Hydride Complexes

Solid-state metal hydrides provide a safe and efficient way of storing hydrogen (Schlapbach 2002). They are commercialized for use in rechargeable batteries and developed for energy conversion devices such as fuel cells (see Hydrogen Metal Systems: Electrochemical Reactions). A great majority of metal hydrides derives from intermetallic compounds and alloys (see Hydrogen Metal Systems: Hydride ...

Ferrocenylalkynes as ligands in transition metal complexes

Several ferrocenylalkynes have been prepared and their reaction with dicobalt octacarbonyl led to the formation of [Co2(CO)6(μ-η 2 : η-ethynylferrocene)] 1, [Co2(CO)6(μ-η 2 : η-1,4-bis(ferrocenyl)butadiyne)] 2, [(Co2(CO)6)2(μ-η : η,μ-η : η-1,4-bis(ferrocenyl)butadiyne)] 3, [Co2(CO)6(μ-η 2 : η-1-ferrocenylethynyl-2-hydro-1,2-dihydro[60]fullerene)] 4, [Co2(CO)6(μ-η 2 : η-1,1’-bis(phenylethynyl)fe...
