title: [Studies of magnetic circular dichroism and absorption spectra in alpha-NisO4 x 6H2O crystal].
abstract: Alpha-NiSO4 x 6H2O crystals were studied by magnetic circular dichroism (MCD) and absorption spectra measurements in the range lambda = 185-3300nm. The results show that there are three aborption bands, of which the peaks are related to the d-d transitions from the ground state to the excited states. The weak peaks of a progression of the three members were observed between the principal structures lambda = 654nm and lambda = 713nm due to spin-orbit coupling interacion. The weak peaks of a progression of four members were also observed around the new absorption peak at lambda = 585nm in MCD spectra.
