Contribution of Charge-Transfer Complexes to Absorptivity of Primary Brown Carbon Aerosol

Determination 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...

determination of trimethoprim based on charge-transfer complexes formation

contribution of setting to the study of characters and the main idea in e. brontes: wuthering heights and t. hardys: return of the native.

this thesis aims to adduce an unmitigated and comprehensive explication concerning the relationship of three significant elements of fiction: setting, chracter and theme. my research is basically placed on two outstanding novels of the 19th century: emily brontes wuthering heights and thomas hardys return of the native. my endeavour lies in studying the correlation among the three above-mention...

Charge transfer complexes of paraquat with drugs

Molecular complexes of paraquat (PQ) with a few drug intermediates in alkaline medium, viz. 2,4,6-trimethylphenol, 4-benzyloxyphenol, 2-cyanophenol, 4-cyanophenol and a few drugs, viz. diclofenac sodium, salmeterol, omeprazole, esomeprazole and pantoprazole in methanol have been studied spectrophotometrically. All the complexes exhibit one charge transfer band each in the region where neither o...

Absorptivity of brown carbon in fresh and photo-chemically aged biomass-burning emissions

Experiments were conducted to investigate light absorption of organic aerosol (OA) in fresh and photochemically aged biomass-burning emissions. The experiments considered residential hardwood fuel (oak) and fuels commonly consumed in wild-land and prescribed fires in the United States (pocosin pine and gallberry). Photochemical aging was performed in an environmental chamber. We constrained the...
