✦ Synopsis

l7 -enriched a-azohydroperoxides, prepared by autoxidation, are efficient 170-labeling reagents; "0 NMRI (CD3CN) of 2 showed broad signals at 6 264 and 204 PPM; the solvent dependence of the 7O chemical shifts and the kinetics of ionic oxidations are interrelated. Despite the relative low receptivity of oxygen in NMR spectroscopy, the large chemical shift range makes it an important nucleus for the study of bonding in organic molecu1es.I Recently, a number of substituent chemical shift correlation studies on conjugated and nonconjugated oxygen systems have appeared.2 However, I70 NJ@ studies of peroxides and hydroper-

## Abstract Oxygen‐17 and nitrogen‐14 nuclear magnetic resonance techniques have been utilized in studying liquid‐state hydrogen bonding interactions between nucleic acid bases and between the bases and solvent. The bases uracil and thymine have been labeled with ^17^O at positions 2 and 4, cytosin

Intercarbonyl dihedral angles have been estimated by molecular mechanics, which show invariance except in one case. Because of this invariance, contrary to other a-dicarbonyl compounds, a correlation between chemical shifts and dihedral intercarbonyl angles could not be developed. Spectroscopic and
