的${L}_{III}}$X射线吸收边的Tm在TmSe产生的温度无关的价2.58\ifmmode\pm\else\textpm\fi{}0.07。TmSe的扩展X射线吸收精细结构的热阻尼与ErSe的热阻尼几乎相同。这表明Tm离子的呼吸壳层电荷波动与声子的耦合非常弱，晶格的静态无序非常小。
The ${L}_{\mathrm{III}}$ x-ray absorption edge of Tm in TmSe yields a temperature-independent valence of 2.58\ifmmode\pm\else\textpm\fi{}0.07. The thermal damping of the extended x-ray absorption fine structure of TmSe is nearly identical to that of ErSe. This indicates very weak coupling of breathing shell charge fluctuations of the Tm ions to the phonons and very little static disorder of the lattice.
