Abstract
A cw dye laser circular dichroism (CD)/absorption apparatus is described and applied to the measurement of an optically active rare earth-organic ligand single crystal. The Nd3+ tris(diglycolate) complex in the NA3(Nd( C4H4O5)3]·2NaClO4·6H2O crystal has been investigated from 12 to 300 K. Absorption spectra at 300 K reveal hot bands from whose positions the crystalfield-split components of the 4I9/2 ground state are deduced. These values are confirmed from the temperature dependence of the peak intensity of the 17184 cm-1 circular dichroism band. The ''4I9/2 state crystal field components are at 0, 20, 200, 320 and 450 cm-1. A weak electron-phonon coupling exists between the Nd3+ ion and the crystal lattice modes.
