Round 1: Tossup 15

Light-induced excited spin-state trapping is used to change energies between sets of these entities via spin crossover. Exchange (10[1])energy is plotted against interatomic distance normalized to the size of one of these entities in Bethe–Slater curves. Unlike MLCT and LCMT bands, transitions between these entities (10[1])are weak (10[1])because they are Laporte forbidden. These entities expand in the nephelauxetic (“NEFF-uh-lox-ET-ic”) effect upon a decrease in the Racah B parameter. (-5[1])The Jahn–Teller effect describes degeneracy (10[1])breaking among the e-sub-g and t-sub-2g (-5[1])sets (-5[1])of these entities obtained from crystal field theory. A torus around two lobes characterizes the z-squared type of these entities. (-5[1])For 10 points, name these entities, partially filled in transition metals, whose energies lie between their p and f counterparts. (10[1])■END■ (0[1])
