Studies in intermolecular energy transfer between certain aromatic bases and 2, 3-dichloro naphthoquinone

Abstract EN

Spectrophotometric studies of intermolecular energy transfer leading to charge transfer complexation between certain aromatic amines, such as N,N-dimethylamine, N-methylamine, p-toluidine, and diphenylamine, and 2,3-dichloronaphthoquinone, have been carried out in chloroform medium.

All the complexes show charge-transfer bands in the visible region, and they form 1:1 complexes of n–II type.

The relevant spectral parameters for the charge-transfer complexes such as association constant, Gibb’s free energy, and molar extinction coefficient are presented.

A comparative study on the evaluation of association constant and molar extinction is investigated by modified B–H, Scott, and F–H–W equations
