本文用质量分析阈电离（MATI）技术研究了芳烃衍生物甲苯、对二甲苯和乙苯的质谱。测量已与传统的反射飞行时间质谱仪进行。这些分子的电离能用7 cm−1的FWHM确定，并与ZEKE光谱测量的值进行比较。此外，一种增加MATI信号强度的新技术已被应用于上述导数的不同中间态。
The aromatic hydrocarbon derivatives toluene, p-xylene and ethylbenzene have been studied using mass analyzed threshold ionization (MATI) spectroscopy. The measurements have been performed with a conventional reflectron time-of-flight mass spectrometer. The ionization energies of these molecules are determined with a FWHM of 7 cm−1 and are compared with the values measured with ZEKE spectroscopy. Additionally a new technique increasing the intensity of MATI signals has been applied to the different intermediate states of the above mentioned derivatives.
