Crystal field energy
WebMar 30, 2024 · In an octahedral environment, the t2g set is the lower set and eg is the higher energy set. The energy separation between these two sets is known as CFSE crystal field splitting energy, denoted by Δ0. Whether a complex will be high spin or low spin, is determined by the magnitude of CFSE. WebJun 29, 2005 · Using both laser-excited fluorescence and optical absorption methods, we have determined 57 crystal-field (CF) energy levels of Sm3+ in crystals of Sm(Et2Dtc)3(bipy). The analysis of the energy levels is based on a model Hamiltonian consisting of both free-ion and CF terms. The CF modeling of the experimental energy …
