- Linear dichroism (LD) results when pseudoisocyanine = PIC (1, 1-diethyl-2,2'-cyanine iodide) binds to flow-oriented DNA. LD may be used to follow the complexation both stoichiometrically and structurally, since when specified to unit complex concentration LD provides a measure of the average orientation of the absorbing transition dipole.Two different types of complexes can be distinguished: I. One strong, ionic-strength insensitive complex with monomeric PIC with an orientation indicating intercalation. II. Several weaker complexes of electrostatic nature (only observed at I
