Paper Abstract

In this paper the dimerization constant of pure hematoporphyrine was established using absorption method and then fluorescence quantum yield ((phi) ) was calculated as a function of monomeric fraction ((alpha) ). It was our objective to formulate an equation describing the relationships between (phi) , (alpha) and ratio of monomer to dimer molar absorption coefficients ((epsilon) M/(epsilon) D), at a given wavelength. (phi) was also studied as a function of pH value and polarity. A 3-D stack fluorescence plot was also constructed and the possibilities of practical application of the fluorescence effect to the visualization of areas with absorbed are presented.
