MAGNETIC CIRCULAR-DICHROISM OF NA3ND(ODA)(3)CENTER-DOT-2NACLO(4)CENTER-DOT-6H(2)O

This paper emphasizes the complementarity between optical and magneto- optical measurements on f elements. The magnetic circular dichroism, c ircular dichroism, and polarized absorption spectra of Na3Nd(ODA)(3) . 2NaClO(4) . 6H(2)O (NdODA), have been recorded at 4.2 K between 5000 and 30 000 cm(-1). The electric dipole contributions to the f-f transi tions are analyzed using a parametric model which contains 12 paramete rs which are determined by fitting the calculated to the empirical dip ole strengths of 50 alpha and 16 pi polarized absorption Lines. The re liability of these intensity parameters is tested by simulating the mo re sensitive magneto-optical (magnetic circular dichroism) and chiropt ical (circular dichroism) spectra.
