## Abstract The complete assignments of the ^13^C NMR resonances of 1‐acetyl‐, 1‐benzoyl‐, 1‐benzenesulphonyl‐, 1‐methanesulphonyl‐ and 1‐(2‐nitrobenzenesulphonyl)‐isatins and their ring‐opened glyoxylic derivatives are reported. The ^13^C assignments of acylisatins were derived from isatin as a mo

The tautomerism and isomerism of triazoles make the structure analysis of such compounds a difficult problem, and in the case of several nitrotriazoles a detailed structure assignment had been lacking up to now. Supported by selected compounds, a deÐnite structure determination of ten nitrotriazoles

## Abstract NMR spectroscopic studies are undertaken with derivatives of 2‐pyrazinecarboxylic acid. Complete and unambiguous assignment of chemical shifts (^1^H, ^13^C, ^15^N) and coupling constants (^1^H,^1^H; ^13^C,^1^H; ^15^N,^1^H) is achieved by combined application of various 1D and 2D NMR spe

## Abstract ^13^C and ^15^N NMR chemical shifts were measured for __N__^1^‐alkyl‐__N__^2^‐arylthioureas. The absence of decoalescence of the __N__^1^‐alkyl group carbon signals down to 190 K, the europium‐induced chemical shifts and the molecular mechanics calculations indicate that the preferred c

## Abstract The pK a values of N-alkyl-N,N-dimethylamine-N-oxides were determined from the pH dependences of chemical shifts in 1H NMR and 13C NMR spectra. The dependences were measured at concentrations below and above the critical micelle concentration of the amine oxides. Above the critical mice
