X-射线光电子能谱(XPS)振起(Shake-Up)伴峰主要是伴随主光电子的电离所导致的最高占有轨道到最低未占有轨道电子跃迁的结果.Carlson及Clark的工作声明这种振起伴峰是某些共轭π电子体系的表征,振起伴峰的相对强度与π电子共轭情况有关。 含酚酞侧基聚芳醚酮(PEK-C)是一种新型耐高温工程塑料,其主侧链均带苯环:
X-ray Photoelectron Spectroscopy (XPS) Shake-Up Companion peaks are the result of electronic transitions from the highest occupied orbital to the lowest unoccupied orbit due to the ionization of the main photoelectron. Carlson and Clark’s work states that this vibration The companion peak is a characterization of some conjugated π-electron systems, and the relative intensities of the resonating companion peaks are related to π-electron conjugation. Phenolphthalein side-chain poly (aryl ether ketone) (PEK-C) is a new type of engineering plastics with high temperature resistance, the main side chains are benzene ring:
