飞行时间质谱计在原子簇分子研究中的运用

Applications of Time-of-Flight Mass Spectrometer to the Studies of Cluster Molecules

摘要: 在现代物理化学研究中,常将多种实验技术结合,应用于对特殊体系的研究。本文介绍了笔者在对原子簇分子与离子的研究中,将飞行时间质谱计与双光子共振电离、激光离解、光电子能谱等实验技术相结合,并与二级飞行时间质谱计和离子回旋加速共振质谱仪串联使用所建立起来的多种实验装置及其研究成果。

Abstract: Time-of flight mass spectrometer (TOFMS) has been extensively used inmodern scientific research. In the studies of metal cluster molecules and ions,several new apparatus have been built, which combined TOFMS with ResonantTwo-Photon Ionization, photodissociation, photodetachment and photoelectronspectroscopy. Tandem TOFMS and TOFMS/FTICRMS are also described in thisarticle. With applications of these new techniques, some excited resultshave been obtained.
