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.
本文研究了全甲基化糖类光谱中最重要的碎片离子（[C5H9O2]+，m/z 101）的结构。通过13C标记的全甲基化葡萄糖呋喃糖苷的光谱定量测定了C-1碳原子在该离子形成中的参与情况。对m/z 101的亚稳离子和碰撞活化光谱的研究为无环离子结构提供了证据。
