摘　　要：在常规质谱中,各种同分异构的稠环芳香烃基本上无法分辨。但在本文报道的以近红外脉冲激光所产生的等离子体质谱中,所分析的四个四稠环芳香烃尽管分子量相同,其负离子质谱却有十分明显的差异,显示了这一研究方法的结构鉴别能力。In a normal mass spectrometer, different polycyclic aromatic isomers can't be distinguished effectively. However, in laser plasma mass spectra achieved on a self-built instrument, the anion mass spectra of four tetracyclic aromatic isomers showed signifigant differences. The illustration of the structural analysis ability of the new-developed mass spectrometry technique was described.
