Reply to the comment on 'Resonance Raman Investigation of Ru(phen)2dppz2+ and Related Complexes in Water and in the Presence of DNA.'
Article Abstract:
Some of the views of J.J. McGarvey, et al, regarding a study on Ru(phen)2dppz2+ and related complexes in water and in the presence of DNA using resonance Raman spectroscopy invite comment. Arguably, the authors' should have determined that the study was based on the effects of pumping in the manifold on the trapping of the excitation at short time scales. In addition, the two excited-state peaks determined in the spectrum of Ru(phen)2dppz2+ were determined from the reduced dppz ligand.

EPR detection of guanine radicals in a DNA duplex under biological conditions: selective base oxidation by [Ru(phen)2dppz](super 3+) using the flash-quench technique
Article Abstract:
Continuous-wave X-band EPR spectroscopy was employed in examining the guanine radical within a DNA duplex at ambient temperature using the flash-quench technique. With ruthenium hexaammine as oxidative quencher, no signal is observed, while, with methyl viologen, a strong signal with hyperfine pattern is seen, characteristic of the reduced viologen radical and indicating that [Ru(phen)2dppz](super 3+) was generated.

Binding of antitumor ruthenium complexes to DNA and proteins: A theoretical approach
Article Abstract:
Model molecules are used for studying the thermodynamics of the binding of the antitumor ammine, amine and immine complexes of ruthenium(II) and ruthenium(III) to DNA and peptides. Bond dissociation enthalpies and free energies are calculated for all metal binding sites both in the gas phase and in solution and have allowed building a binding affinity order for the considered nucleic acid or protein binding sites.
