摘要
研究了八种 N-二茂铁甲基苯胺衍生物的电子电离质谱 (EI- MS) ,并与快原子轰击质谱 (FAB- MS)作了比较 ,讨论了这些化合物的质谱特征。通过精确质量测量 ,确认了 M+ · - 2 OH离子 ,并采用碰撞诱导裂解 (CID)探讨了化合物质谱中主要离子间的关系。
In this paper, the electron ionization (EI) mass spectra of N-ferrocenylmethylaniline derivatives were studied. By comparing with their fast atom-bombardment (FAB-MS), we discussed the MS characteristics of these compounds. Ions M +-2OH were identified by peak matching methods. In addition, the relationships of fragment ions were further demonstrated by collision induced dissociation (CID).
