本文简要综述了Friburg最近研究的三个主题:(I)电子与离子液体表面的碰撞,(Ii)二维(2D)电子能量损失谱和(Iii)不饱和化合物电子激发的绝对截面上的共振。四种离子液体的电子能量损失谱显示了许多激发态,包括三重态。染料在离子液体中的溶液显示出溶质的能量损失带,但不是在所有离子液体中。二维谱揭示了态到态的信息(给出了给定的最终态的共振),并被证明是一种有趣的手段,可以在共振中洞察核运动的动力学。报道了作为散射角和电子能量函数的嘧啶的绝对截面。它们揭示了共振结构,并通过R矩阵计算很好地再现了这一结构。计算提供了一个共振峰的赋值,它揭示了含有双键的化合物中的常见模式。
AbstractThe article briefly reviews three subjects recently investigated in Fribourg: (i) electron collisions with surfaces of ionic liquids, (ii) two-dimensional (2D) electron energy loss spectra and (iii) resonances in absolute cross sections for electronic excitation of unsaturated compounds. Electron energy loss spectra of four ionic liquids revealed a number of excited states, including triplet states. A solution of a dye in an ionic liquid showed an energy-loss band of the solute, but not in all ionic liquids. 2D spectra reveal state-to-state information (given resonance to given final state) and are shown to be an interesting means to gain insight into dynamics of nuclear motion in resonances. Absolute cross sections for pyrimidine are reported as a function of scattering angle and as a function of electron energy. They reveal resonant structure which was reproduced very nicely by R-matrix calculations. The calculation provided an assignment of the resonances which reveals common patterns in compounds containing double bonds.Graphical abstract
