摘要双取代苯的结构异构体很难用大多数质谱方法区分。因此，区分异构体的传统概念是基于质谱法与色谱法的耦合。作为一种替代方法，我们建议将飞秒激光电离与飞行时间质谱（fs-LIMS）相结合。系统剪裁fs激光脉冲形状的可能性打开了一种多维分析技术的大门，能够区分标题分子的结构异构体。
Abstract Structural isomers of disubstituted benzenes are difficult to distinguish with most mass spectrometric methods. Consequently, conventional concepts for the distinction of isomers are based on coupling mass spectrometry with a chromatographic method. As an alternative approach, we propose the combination of femtosecond laser ionization with time-of-flight mass spectrometry (fs-LIMS). The possibility of systematic tailoring of fs-laser pulse shapes opens access to a multidimensional analytical technique capable of distinguishing structural isomers of the title molecules.
