【Abstract】 The negative ion electron impact mass spectra (NIEJ-MS) and their cleavage in somephosphonothionates were discussed on the basis of low resolution mass spctral and meta-stable ion analysis. It is found that the property and the position of the substituentshave a marked influence on the isomeric rearrangement of the phosphonothionate.更多还原
