It is now possible to review the conformational and electronic behaviours of the isomers of chalcogenobispyridines and related compounds, so providing information on the link between the geometric and electronic properties, and providing some insight

The He I and He II photoelectron spectra of the symmetrical isomers of dipyridyl disulfide and diselenide have been measured and interpreted in terms of a composite-molecule model. The sequence of the lowest valence ionisation energies is assigned as

The He I photoelectron spectra of 2-, 3- and 4-methoxypyridine are reported and interpreted in terms of a composite-molecule model and ΔSCF/MP ionization energies. For pyridine, this ab initio method correctly locates the nitrogen lone-pair molecula

The conformational behaviour of the tellurobispyridines had been investigated using the ab initio STO-3G * //STO-3G * model, which reveals that the minimum energy conformers are not planar and that energy barriers between 6 and 50 kJ mol −1 restric
