It also analyzes the differences in fragmentation pathways when they have lithium or a proton attached. Methods used include mass-spectrometry, MS/MS and pseudo-MS. After the experiments and evaluation several common dissociation paths were established, as well as several characteristic differences between lithiated and protonated compounds.28enchemistrymass-spectrometryanalysisChemistry::Applied ChemistryHozzáférhető a 2022 decemberi felsőoktatási törvénymódosítás értelmében.
