## Abstract The ^13^C chemical shifts of 37 pyrazines, including their __N__βoxides, are reported. Substituent effects of methyl, phenyl and __N__βoxide groups on the chemical shifts were examined. To comprehend these effects, the chemical shifts were compared with charge densities calculated by th

## Abstract ^13^C NMR data are reported for new __N__βbenzyl and __N__βalkyl derivatives of 3βazachalcone. The unambiguous assignment of signals is based on ^13^C/^1^H heteroshift correlated 2D NMR spectra.
## Abstract Ascorbic acid (1a), the 6βbenzoate and 6βpalmitate ester (1b, c) were oxidized by iodine both in D~2~O and in [D~6~]DMSO solution. The reactions were followed by ^13^CβNMR spectroscopy. It was shown for the 6βesters 1b, c, that, with the exclusion of water, monomeric dehydroascorbic aci
The 13C NMR spectra of the isomeric alkaloids lupinine and epilupinine and their perchlorates, methiodides and N-oxides are discussed. Chemical shift changes due to protonation, quaternizatiOn and N-oxidation are andysed. The trans-quinolizidine ring fusion is proved for epilupinine salts and for th
