Perturbation theory degenerate case
Webcontains as special cases: (i) the Schrodinger-Brillouin formula for the eigenvalue of a nondegenerate state, (ii) a new simple formula for treating a class of degenerate states, … WebThe ZFS parameters were calculated through the quasi-degenerate perturbation theory [40,41,42]. Relativistic effects were taken into account by using the zeroth-order regular approximation [ 43 , 44 ] together with the corresponding segmented all-electron relativistic contracted version of the triple-ζ basis set Def2-TZVP [ 45 ] for all atoms.
