报道了在200、220和240 eV的光子能量下S 2 p（-1）光电离后羰基硫的高分辨率正态俄歇电子谱以及相应的光电子谱。沿着。此外，理论结果考虑到各种自旋轨道分裂和分子场分裂的S2 p（-1）态的核心-空穴取向。观察到八个亚稳双阳离子末态的俄歇跃迁，并根据理论结果进行了归属。从Franck-Condon分析，假设莫尔斯势沿着正常坐标的七个观察到的准稳定双阳离子的最终状态，信息的势能面推导出，并与文献中的理论结果进行了比较。
High-resolution normal Auger-electron spectra of carbonyl sulfide subsequent to S 2p(-1) photoionization at photon energies of 200, 220, and 240 eV are reported along with corresponding photoelectron spectra. In addition, theoretical results are presented that take the core-hole orientation of the various spin-orbit-split and molecular-field-split S 2p(-1) states into account. Auger transitions to eight metastable dicationic final states are observed and assigned on the basis of the theoretical results. From Franck-Condon analysis, assuming Morse potentials along the normal coordinates for seven of the observed quasi-stable dicationic final states, information on the potential-energy surfaces is derived and compared with theoretical results from the literature.
