Abstract
Magnetic circular dichroism (MCD) studies are reported on several metal d10s2 systems both in solutions at room temperature and as dopants in crystals at room temperature and liquid helium temperature. Magnetic moments of the excited T1u(3P1) state obtained from the data are considerably lower than theoretically expected for octahedral complexes and suggest substantial quenching of angular momentum probably, at least in part, through the participation of the metal p orbitals in covalent bonding. The T1u(1P1) region clearly indicates distortion from high symmetry in most cases with apparent complete quenching of the angular momentum in the excited state. In addition, high resolution MCD data are presented on Cs2ZrCl6: Os4+ at liquid helium temperature. A vast amount of fine structure is revealed often exceeding in clarity the previously studied absorption spectrum. A preliminary analysis of the results is discussed.Keywords
