title: The distribution of nucleic acid chromophores at cellulose-water interfaces. 1. Photometric parameters.
abstract: A computer-assisted calculus of the chromophores distribution in the contiguous layer around the scattering centers of a multiple scattering medium, using bichromate photometric data and an extended Kubelka-Munk expression, was developed. Explanatory examples of nucleic acid impregnated chromatography paper disks show the efficiency of the method proposed for the study of macromolecular structures and the dependence upon the physico-chemical peculiarities of the solutions used.
