Outline of Final Research Achievements |
New molecular structural characterization technique using an energy-resolved ion-mobility mass spectrometry (ER-IMS-MSn) was developed in the period. Data mining for the relationship between stability of the gas phase ion structures and ER-IMS MSn spectra was used to elucidate the structural characterization of cyclic molecules,such as depsipeptides. Ion isomerization during the collision activation experiments was obvious for relatively stable alkaline metal addition ions. So that, alkaline addition ions were suitable for the ion structural characterization.This technique enabled us to obtain additional structure information using mass spectrometry.
