Resonance Electron Attachment to Glucose and Fructose Molecules
- 46 Downloads
Low-energy negative ion mass spectra of glucose and fructose suggest the deep fragmentation of short-lived molecular ions. An analysis of metastable ions in the mass spectra shows that some decomposition reactions proceed through intermediate [M–H2O]–, etc. ions. Along with the general similarity of the ionization processes in the isomers, there is a significant difference, which is in the intensive formation of m/z 71 ions from glucose.
