UV-spectral changes for some azo compounds in the presence of different solvents
(Elsevier Science BV, 2011)
The electronic absorption spectra of four azo dyes with different substituents (such as Cl, I, OH) are determined at room temperature in twenty-one solvents with different polarities. The electronic transitions of azo dyes ...
A study on solvatochromism of some monoazo dye derivatives
(Elsevier Science BV, 2013)
The UV-vis and fluorescence spectra of four monoazo dye derivatives were investigated in the solvents with different polarities. Characterization of UV-vis electronic bands is specified by calculating charge transfer energy ...
Spectroscopic Determination of Acid Dissociation Constants of Some Novel Drug Precursor 6-Acylbenzothiazolon Derivatives
(American Chemical Society, 2010)
The acid dissociation constants, as pK(a) values, of eight drug precursor 6-acylbenzothiazolon derivatives were determined using UV-vis spectroscopic technique. The protonation and deprotonation behaviors of the investigated ...
