The low-temperature absorption and excitation spectra of interconfigurational 4f-5d transitions of Tb(3+) in a cubic fluoride host demonstrate the appearance of a first-order linear Jahn-Teller effect for the high-spin excited states of the excited electronic configuration 4f(7)5d involving 5d t(2g) orbitals. The τ(2g) mode is observed to be responsible for the splitting of the otherwise degenerate 5d t(2g) orbitals.
低温下立方氟化物基质中 Tb(3+) 的内组态 4f-5d 跃迁的吸收和激发光谱表明，在涉及 5d t(2g)轨道的激发电子组态 4f(7)5d 的高自旋激发态中，出现了一阶线性 Jahn-Teller 效应。τ(2g)模式被观察到负责分裂原本简并的 5d t(2g)轨道。
