There are several methods for fine resolution of convoluted spectra. The most important techniques are treated briefly in this section.

Both, natural pigments and synthetic organic pigments and dyestuffs have been treated in numerous publications. The fine-resolution of spectra by differentiation makes this technique a particularly powerful tool for identification and for verifying quality and purity (Table 5-16 and 5-26).
