多原子共振(MAR)是指一个原子的核-电子发射受到邻近原子的核-价共振激发的扰动。在这里,我们研究了简单二元化合物在固体和水溶液中的MAR。对于固体CaCl2,当入射X射线的能量调谐到相邻CaK边的共振能量时,ClKαX射线的强度降低,而CaCl2的水溶液没有观察到这样的强度降低。对于KCl2和SrCl2也得到了类似的结果。由于我们可以用这种方法来确定邻近原子的原子物种,所以我们可以用这种方法来确定邻近原子的原子物种。这些观察到的现象将为一种新的结构分析铺平道路,该结构分析是对基于同步加速器的X射线能谱的补充,如扩展X射线吸收精细结构(EXAFS)和X射线吸收近边结构(XANES)。
Multi-atom resonance (MAR) is a phenomenon where core-electron emission from an atom is perturbated by the core-to-valence resonant excitation in the neighboring atom. Here, MAR’s in simple binary compounds were investigated both for solid and aqueous solution. For solid CaCl 2, it was found that the intensity of Cl K α X-rays was reduced when the energy of the incident X-rays was tuned at the resonance energy of the neighboring Ca K-edge, but such intensity reduction was not observed for aqueous solution of CaCl 2. Similar results were also obtained for the KCl and SrCl 2. Since we can determine the atomic species of the neighboring atom by this method, the observed phenomena will pave a way to a new structural analysis that is complimentary to the synchrotron-based X-ray spectroscopies such as extended X-ray absorption fine structure (EXAFS) and X-ray absorption near-edge structure (XANES).
