Direct determination of zero-field splitting in Co(II) complexes by FAR infrared spectroscopy
چکیده انگلیسی

Three centrosymmetric, mononuclear cobalt(II) complexes possessing large zero-field splitting parameter D have been studied by means temperature-dependent FAR infrared spectroscopy. From 15 temperature-dependent absorption peaks referring to the transition between the six lowest crystal-field multiplets the value of the D-parameter has been directly read off. These data are comparable with those values extracted by fitting the magnetic susceptibility and magnetization data.
