<p>The electronic structure of a chiral Yb(III)-based complex is fully determined by taking advantage of experimental magnetic, luminescence, and chiroptical characterizations in combination with ab-initio wavefunction calculations. The combined use of these techniques allows determining with high resolution the electronic structure diagram as well as the nature of the different states involved in the magnetic and chiroptical properties of the investigated complex. The different crystal-field pictures deduced from spectroscopic measurements are re-conciliated in light of the magnetic properties and ab-initio results in the frame of the van Vleck initial vision. Advanced ab-initio calculations demonstrate that global chiroptical spectra correspond to the sum of intricated transitions with similar or opposite polarizations.</p>

The electronic structure and magnetic properties of a series of Kramers ions with f1 configuration in axial symmetry have been analyzed with a combination of theoretical methods: ab initio relativistic wavefunction methods as well as a crystal-field (CF) model with parameters extracted from the ab initio calculations.

AbstractAb initio calculations using SCF approach for and analysis of results of investigation of the electronic structure of the clusters RA+n:[L]k with rare earths or actinides were carried out for the clusters in solids and liquids. Theoretical results for the electronic structure, radial integrals and energy of X- ray lines are presented for AC ions with unoccupied 5f-shell in the clusters in oxides, chlorides and fluorides environment. Possibility of collaps of nf-shell for the separate clusters and identification of electronic state of ions with unstable nuclei, are discussed, too.
