Desorption chemical ionization mass spectrometry of twelve metallohematoporphyrin complexes has been investigated under DEP condition using mixture of tetramethylsilane and methane as regent gas.

本文以硅烷／烷混合反应气，采用DEP技术，测定12个金属血卟啉络合物的解化学电离质谱。

Based on these results and the ESI-MS data, the mechanism of sulfoxidation was proposed to be intramolecular nucleophilic oxygen transfer to a coordinated sulfide.

于这些结果和电喷雾质谱(ESI-MS)数据，亚砜化反应的测为分子内亲核氧转移到络合的硫醚底物上。
