Herein, a systematic microscopic investigation of the crystal-field (CF) effects on Mn4+ ions doped at triclinic sites in the double perovskite La2ZnTiO6 crystal was performed using two independent modelling approaches based on CF theory: the exchang

By using crystal field theory, the spin-Hamiltonian parameters [zero-field splitting D, the giromagnetic factors g (g || and g ⊥) and the first excited state splitting δ(2 E)] for the CrLi 3+ doped in LiNbO3 have been calculated from the higher-or

Within this study we have calculated the surface fractal dimension (Ds) and the backbone fractal dimensions associated to the local folding (D1) and to the global folding (D2) for two unbiased sets of 50 proteins each, one for monomer and the other f

In the present paper we report on an analysis of the fine structure of the first excited quartet 4T2g of Mn4+ ions which occupy the octahedral site in the Cs2GeF6 host crystal. The dynamic 4T2g⊗(eg+t2g) Jahn-Teller effect is considered in details,

For an octahedral system, we analyzed the coupling between the triple degenerate electronic states of a transition metal ion and the double degenerate vibration of the ligands of the host matrix. The vibrations of the ligands of the lattice are descr

The coupling between doubly degenerate electronic states and doubly degenerate vibrations is analyzed for an octahedral system on the basis of the introduction of an anharmonic Morse potential for the vibronic part. The vibrations are described by an
