✦ Synopsis
The absolute configuration of the 2-(phenylmethy1)pyridine derivatives 1-9 had been established by X-ray diffraction and chemical correlation. Their CD spectra have been studied in different solvents for the free and protonated forms. It has now been found that, from the sign of the strong CD couplet between 270 and 220 nm, which was observable for all these compounds besides 7 and 9, their absolute configuration can be determined much quicker.

The MCD spectra of hexachlorobemede, 1,3,5-t~ichlorobenzene, hexabromobenzene and 1,3,5-triiromobenzene have been measured. For each molecule, the Faraday A term was observed in the region of the \*At& 'Etu transition and thereby the magnetic moment in the \*E tu state was extracted. It appears that
