Abstract: | The long‐wavelength magnetic circular dichroism (MCD) spectra of some nitrogen‐containing heteroconjugated aromatic compounds have been recorded and interpreted on the basis of quantum‐chemical model calculations. In particular, the dependence of the MCD bands on the positions of the N‐atoms inside the aromatic rings and on substituents has been investigated. Some of the compounds considered form Ru2+ complexes. The influence of complexation on the long‐wavelength π‐π* bands of the ligands has also been recorded and discussed. |
