Similar features in the absorption and satellite hole spectra of thionin in the presence of calf thymus (CT) DNA and polynucleotides [d(GC)(6)](2) (GC) suggested that thionin preferentially binds to GC rather than polynucleotides [d(AT)(6)](2) (AT). Different binding effects of the two tautomers to DNA could be observed. While the imino form fully intercalates into the DNA base pairs, the amino form is only partially intercalated. In addition, a broad hole associated with an antihole appeared in the presence of DNA, particularly in GC base pairs. The coincidence of the antihole with the absorption band of the amino form showed that the amino form is the photoproduct of the imino form. An increase in intensity of the broad hole and its antihole and the loss of nonresonant hole intensity upon interaction with CT DNA could be described by rapid ground state recovery resulting from fast charge transfer between the intercalated thionin and a guanine base quenching the internal conversion.
