[1] CT absorptions bands are intense and often lie in the ultraviolet or visible portion of the spectrum. For coordination complexes, charge-transfer bands often exhibit molar absorptivities, ε, of about 50000 L mol −1 cm −1. By contrast ε values for d–d transitions are in the range of 20–200 L mol −1 cm −1.
In chemistry, charge-transfer (CT) complex, or electron donor-acceptor complex, describes a type of supramolecular assembly of two or more molecules or ions. The assembly consists of two molecules that self-attract through electrostatic forces, i.e., one has at least partial negative charge and the partner has partial positive charge, referred ...
Protein folding problem: Is it possible to predict the secondary, tertiary and quaternary structure of a polypeptide sequence based solely on the sequence and environmental information? Inverse protein-folding problem: Is it possible to design a polypeptide sequence which will adopt a given structure under certain environmental conditions?
The cation obeys the 18-electron rule and is considered to be a classic example of an exchange inert metal complex. As a manifestation of its inertness, [Co(NH 3) 6]Cl 3 can be recrystallized unchanged from concentrated hydrochloric acid: the NH 3 is so tightly bound to the Co(III) centers that it does not dissociate to allow its protonation.

Cis-dichlorobis(ethylenediamine)cobalt(III) chloride is obtained by heating a solution of trans-dichlorobis(ethylenediamine)cobalt(III) chloride, e.g. using a steam bath.
In chemistry, a molybdate is a compound containing an oxyanion with molybdenum in its highest oxidation state of +6: O − −Mo(=O) 2 −O −. Molybdenum can form a very large range of such oxyanions , which can be discrete structures or polymeric extended structures, although the latter are only found in the solid state.
In chemistry, racemization is a conversion, by heat or by chemical reaction, of an optically active compound into a racemic (optically inactive) form. This creates a 1:1 molar ratio of enantiomers and is referred to as a racemic mixture (i.e. contain equal amount of (+) and (−) forms). Plus and minus forms are called Dextrorotation and ...
The integrated areas are compared to a calibration curve, created using standards' concentrations to calculate the concentration of each component in the unknown sample. Data Interpretation: The software analyzes the integrated data to draw conclusions about the composition, concentration, and purity of the sample. The integrated areas provide ...
