The structure of the m/z 101 ion in the spectra of permethylated saccharides.
In this paper the structure of the most important fragment ion ([C5H9O2]+, m/z 101) in the spectra of permethylated saccharides is investigated. The participation of the C-1 carbon atom in the formation of this ion has been quantitatively determined from the spectra of 13C labelled permethylated glucofuranosides. Investigation of the metastable ion and collisional activation spectra of m/z 101 yielded evidence for an acylic ion structure.
