Abstract
'H and 13 C NMR spectra of isoguanine (2-hydroxyadenine) and 8-oxoadenine in H 2 O and DMSO-d 6 solutions of various acidity have been interpreted using arguments based on the results of several 1D and 2D NMR experiments and theoretical DFT-based calculations. The collected data for H 2 O solutions can serve for identification of these compounds in body fluids during medical analysis. The 'H and 13 C NMR spectra of the investigated compounds in DMSO-d 6 solutions have provided information on their tautomeric forms and the mobility of their exchangeable protons.
