Ion-mobility peaks of sesamin isomers were separated as their lithium adduct molecules [M+Li]+. The drift time of sesamin was the latest, that of episesamin was the next, and that of diasesamin was the earliest in the ion-mobility MS specta. Their conformations were calculated from the ion-mobility data with quantum calculation.
