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

## Abstract The ^13^C NMR data for tricyclic and bicyclic diaziridines with condensed five‐ and six‐membered rings are interpreted and compared with the forecast of the C13‐NMR/IR data‐base (successor: SPECINFO data‐base). There are large differences in chemical shifts and large deviations in the f
The 'H NMR spectrum of pentafulvalene has been analysed. Proton-proton coupling constants and I3C chemical shifts are compared with those of sterically similar pentafulvenes. Pentafulvalene can be regarded as a pentafulvene with a highly localized n-system.
