Presentation Abstract
Two-photon absorption (TPA) line strengths for transitions within the 4f7 configuration of Gd3+ have been determined directly using a two-configuration 4f7 and 4f65d calculation. This direct calculation takes into account the major interactions for the 4f7 and 4f65d configurations nonpertubatively. Contributions from dynamic coupling (also called ligand polarization) are found to be important in order to reconcile calculated and experimental spectra for the 8S7/2 → 6IJ transitions. Resulting calculated TPA spectra are shown to give a good reproduction of experimental line strengths and polarization dependencies.
