## Abstract The aromatic ^1^Hโ and ^13^CโNMR. spectra of some metal complexes of o, oโฒโdihydroxyazobenzenes are shown to be useful in distinguishing the two possible isomers (acolar and discolar) stemming from the non equivalence of the two ligating azo nitrogen atoms. The ortho aromatic carbon ato

## Abstract ^77^Se and ^13^C chemical shift of 19 1,2,3โselenadiazoles are discussed in terms of substituent effects and conformaโtional behaviour of the molecules. It is shown that the ^77^Se chemical shifts of such compounds are suitable tools for chiral discrimination in diastereomeric compounds
## Abstract Chemical shifts and substituent chemical shift (SCS) effects are reported for 21 monosubstituted isoโquinolines, carrying a halogeno, amino, piperidino or ethoxy group in position 1, 3 or 4. In some cases, assignments of ^13^C resonances were based on the spectra of the corresponding 5โ
The "C NMR spectra of eight novel derivatives of bicydo[2.2.2]-and -[3.2.l]octane have been recorded and analysed. Tbese compounds were isolated and characterized as intermediates in the synthesb of a unique derivative of 1,2,3,3a,llb,llc-hexahydroahydroaporphine. Carbon chemical shift assignments o
