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 ...
The optical spectrum of this d 6 octahedral complex exhibits an intense absorption near 250 nm corresponding to a transition from ligand σ MO to the empty e g MO. In IrBr 6 2−, which is a d 5 complex, two absorptions, one near 600 nm and another near 270 nm, are observed.
Iodine trichloride, which exists in the solid state as the planar dimer I 2 Cl 6, is a bright yellow solid, synthesised by reacting iodine with liquid chlorine at −80 °C; caution is necessary during purification because it easily dissociates to iodine monochloride and chlorine and hence can act as a strong chlorinating agent.
In chemistry, ion association is a chemical reaction whereby ions of opposite electric charge come together in solution to form a distinct chemical entity. [1] [2] Ion associates are classified, according to the number of ions that associate with each other, as ion pairs, ion triplets, etc. Ion pairs are also classified according to the nature of the interaction as contact, solvent-shared or ...

[1] [2] Mass spectra is a plot of relative abundance against mass-to-charge ratio. It is commonly used for the identification of organic compounds from electron ionization mass spectrometry . [ 3 ] [ 4 ] Organic chemists obtain mass spectra of chemical compounds as part of structure elucidation and the analysis is part of many organic chemistry ...
Ionic conduction [ edit ] Similar to electron conduction, the electrical resistance of thin-film electrolytes depends on the applied electric field, such that when the thickness of the sample is reduced, the conductivity improves due to both the reduced thickness and the field-induced conductivity enhancement.
Ion interaction chromatography (ion-pair chromatography) is a laboratory technique for separating ions with chromatography. In this technique ions are mixed with ion pairing reagents (IPR). [ 1 ] The analyte combines with its reciprocal ion in the IPR, this corresponds to retention time .
