Abstract:
Previous characterization of the double-well E3Σ1+63S1 - Rydberg state outer potential well E3Σ1out+ in CdAr van der Waals (vdW) complex has been based on detection of the E3Σ1+←B3Σ1+53P1 (υ″=0-2) transitions only. In this study, the gap in the limited characterization of the E3Σ1+out shallow well and the neighbouring potential barrier has been filled by recording bound (υ') ← bound (υ″=1-4) and free ← bound (υ″=0-4) excitation spectra. The result, spectroscopic description of the E3Σ1out+ well along with the potential barrier have been concluded from simulations of the recorded spectra. The results were compared with those published previously.

Crystal Field Theory - Octahedral Complexes
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.

Crystal Field Theory - Tetrahedral and Square Planar Complexes
Crystal field theory (CFT) is applicable to molecules in geometries other than octahedral. In octahedral complexes, the lobes of the dx2−y2 and dz2 orbitals point directly at the ligands. For tetrahedral complexes, the d orbitals remain in place, but with only four ligands located between the axes. None of the orbitals points directly at the tetrahedral ligands. However, the dx2−y2 and dz2 orbitals (along the Cartesian axes) overlap with the ligands less than the dxy,...
