## Abstract The ^13^C n.m.r. spectrum of benzofuroxan at −15°C is assigned on the basis of selective decoupling experiments and by comparison with the ^13^C chemical shifts of model compounds. The ^13^C spectra were also measured in trifluoroacetic acid as a solvent. From the temperature dependence

Abstract
Complete assignments are made for 23 4‐quinolones and related compounds. Literature data are used to calculate chemical shifts for 17 of these compounds: calculated and experimental shifts are in excellent agreement—all within 5 ppm for nine of the compounds and a maximum discrepancy of 7.6 ppm.

## Abstract The ^13^C chemical shifts and one‐bond carbon‐hydrogen coupling constants have been obtained for some hydroxycoumarins and their corresponding acetoxy and methoxy derivatives. The changes in the one‐bond carbon‐hydrogen coupling constants resulting from the conversion of a hydroxy group
A series of 14 3-substituted 4-oxoquinolones with or without a substituent (methyl, ethyl) in position 1 were prepared. Literature and measured data were used to study the inÑuence of the substituent on the shifts of carbon atoms of these compounds, which are model compounds for antibacterial drugs
## Abstract A series of 2‐ and 4‐quinolones substituted in the hetero‐ring have been evaluated using ^13^C NMR techniques. Substituent effects are discussed as an aid to evaluation of potential tautomerization in the 2‐quinolone systems. The observed substituent shifts for systems having a hydroxy
## Abstract The ^1^H and ^13^C chemical shifts, proton‐proton coupling constants, and one‐bond carbon‐hydrogen coupling constants have been obtained for 7‐azaindole, 1‐methyl‐7‐azaindole, their corresponding methyl iodide salts, and the related compound 7‐methyl‐7__H__‐pyrrolo [2,3‐__b__]pyridine.
