title: Relation between differential pulse voltammetric oxidation of polyriboinosinic acid and its structure.
abstract: Electrooxidation of poly (I) at a paraffin wax-impregnated spectroscopic graphite electrode was studied by means of differential pulse voltammetry. It was found that the transition of single-stranded poly (I) to its multistranded form, induced by increasing the ionic strength of neutral medium, is accompanied by a lowering of the oxidation current of poly (I). The marked lowering of the oxidation current is also observable as a consequence of the formation of double-stranded complex of poly (I). poly (C). The voltammetry at carbon electrodes provides for the study of poly(I) structure in principle identical information as optical methods.
