متن کاملFemtosecond 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...
متن کاملEvidence that the spectral dependence of light absorption by aerosols is affected by organic carbon
[1] The wavelength dependence of light absorption by aerosols collected on filters is investigated throughout the near-ultraviolet to near-infrared spectral region. Measurements were made using an optical transmission method. Aerosols produced by biomass combustion, including wood and savanna burning, and by motor vehicles, including diesel trucks, are included in the analysis. These aerosol ty...
متن کاملBlack carbon or brown carbon? The nature of light-absorbing carbonaceous aerosols
Although the definition and measurement techniques for atmospheric “black carbon” (“BC”) or “elemental carbon” (“EC”) have long been subjects of scientific controversy, the recent discovery of light-absorbing carbon that is not black (“brown carbon, Cbrown”) makes it imperative to reassess and redefine the components that make up lightabsorbing carbonaceous matter (LAC) in the atmosphere. Evide...
متن کاملDetermination of Trimethoprim Based on Charge-Transfer Complexes Formation
A spectrophotometric study concerning the interaction between Trimethoprim (TMP) ,Sulfamethoxazole (SFMx), as n-donor and 2,3-dichloro-5,6- dicyano-P-benzoquinine (DDQ) and chloranilic acid (CA) as π-acceptor were been performed at 25°C. The results of interaction of CA and DDQwith TMP indicate the formation of a 1:1, 1:2, charge transfer complexes through non equilibrium reactions. In the case...
