The absorption and circular dichroism spectra of the intercalation
complexes with DNA of the 9-aminoacridine chromophore
in mono- and bisfunctional forms have been determined in the
visible/near-ultraviolet region. The experimental spectra were
deconvoluted into contributions from three (It*, n) transitions and
the dipole and rotatory strengths of one long-axis and one shortaxis
polarized transition were determined for each intercalating
species. The experimental results were compared with theoretical
calculations of the induced CD of intercalation complexes and a
series. of inferences were drawn concerning the geometry of the
complexes.
