The use of spectrophotometry UV-Vis for the study of porphyrins

In the porphyrins study, the evaluation of wavelength shift of adsorption bands and the absorbance changes as function of pH, temperature, solvent change, reaction with metal ions and other parameters permits to obtained accurate information about equilibrium, complexation, kinetic and aggregation. This chapter of the book, resumes the best successes in the use of UV-Vis spectrophotometry for explained the chemical characteristics of this extraordinary group of natural occurring molecules and clarifies the potential of these molecules in many fields of application
