The experimental dipole strengths for the f-f transitions in the axial and polarized orthoaxial absorption spectra for Eu3+ in the scheelite type matrix LiYF4 are given. The line intensities are explained assuming a D2d symmetry around the Eu3+ ion. The induced electric dipole transition intensities are simulated by means of a set of B-lambda kq intensity parameters. The quantitative evaluation of the A-terms in the MCD spectra provides a valuable tool for checking the reliability of the crystal held wavefunctions and the intensity parameters.
