摘要: Abstract A semi empirical method for the resolution of absorption spectra three ionic azo dyes (Acid Red 266, Congo and Benzopurpurine 4B) in monomeric state has been applied. The were measured ethane-1,2-diol to ensure a since water as solvent aggregation phenomena lead non-equidistant peak positions (measured cm−1) corresponding sub-bands. recorded represented by sum 6 symmetrical Gaussian bands, (νi) which related respective vibronic intervals (Δνvib), revealed derivative spectroscopy minimise an arbitrary choice fitting parameters.
