利用同步辐射光电高质谱法对间硝基本胶（C6H6N2O2）进行了研究；测得了其电离势IP（C6H6N2O2）为966±0.05ev，以及一些碎片离子出现势AP，计算出了离解能D0（N2O－C6H6N+)和离子生成焓△Hf（C6H6N＋）.给出了间硝基苯胜的同步辐射光电离质谱图，并对主要碎片离子的产生过程进行了初步分析．
The synchrotron radiation photoelectron high mass spectrometry (GC-MS) was used to study the intergranular basic gum (C6H6N2O2). The ionization potential IP (C6H6N2O2) was found to be 966 ± 0.05ev and some APs appeared. The dissociation energy D0 -C6H6N +) and the ion formation enthalpy △ Hf (C6H6N +). The synchrotron radiation photoionization (MS) spectra of m-nitrophenylsulfonic acid were given and the generation of major fragment ions was analyzed.
