- 中文摘要: The mass spectra of twenty-nine sydnones were measured by using NH/sub 3/ as a reagent gas. The(M+H+NH/sub 3/)/sup +/ ions are the base peaks for the entire series. Very few fragment ions were observed except for the derivatives of 4- hydroxymethylenesydnones. Only the relatively stable sydnonyl-methylene cations are formed. With consistent formation of (M+18)/sup +/ ion as the base peaks with simple spectra, the NH/sub 3/ CI-MS can be an excellent method for the molecular weight determination.
