This simplicity is emphasized by the recent use of DPPH· to assess the stability of drug candidates toward reaction with oxygen and oxygen-centered radicals at an early stage in the drug development process; see: Karki, S. B.; Treemaneekarn, V.; Kaufman, M. J. J. Pharm. Sci. 2000, 89, 1518-1524.

Interestingly, DFT calculations on 6/HBA complexes have revealed that the O-H stretching frequencies for the intermolecular hydrogen-bonded complexes are almost identical for the "HO-away-from-MeO" conformer. i.e., the simple intermolecular H-bond, as for the "HO-toward-MeO" conformer, i.e., the trifurcated inter-intra hydrogen bond; see footnote 34 in ref 11.
