## Abstract The ^13^C NMR spectra of four pairs of 1,3,4โthiadiazole/thiadiazoline isomers have been recorded using broad band and offโresonance proton decoupling techniques and in the coupled mode. Differences in the chemical shifts of the heterocyclic ring and the carbonyl carbons allow identific

## Abstract The analysis of the ^13^C FT NMR spectra of 2โhetera[3](1,1โฒ)ferrocenophanes containing an oxygen, sulphur, selenium atom, phenylโsubstituted nitrogen or a methylene group in the 2โposition of the bridge has been carried out. The electronegativity of this fragment affects both chemical
