The location of the Pd atoms in Pd2Au36(SC2H4Ph)24, is studied both experimentally and theoretically. X-ray photoelectron spectroscopy (XPS) indicates oxidized Pd atoms. Palladium K-edge extended X-ray absorption fine-structure (EXAFS) data clearly show Pd-S bonds, which is supported by far infrared spectroscopy and by comparing theoretical EXAFS spectra in R space and circular dichroism spectra of the staple, surface and core doped structures with experimental spectra.
Pd2Au36(SC2H4Ph)24 中 Pd 原子的位置通过实验和理论进行了研究。X 射线光电子能谱（XPS）表明 Pd 原子被氧化。钯 K 边扩展 X 射线吸收精细结构（EXAFS）数据清楚地显示了 Pd-S 键，这得到了远红外光谱和比较理论 EXAFS 谱在 R 空间和 staples、表面和核心掺杂结构的圆二色光谱与实验光谱的支持。
