Electrospray ionization (ESI) of an aqueous solution of α‐cyclodextrin (α‐CD) gave a protonated molecule, [α‐CD + H]⁺. The fragmentation behavior of the protonated molecule, including direct decomposition and ring cleavage, was investigated by varying the source fragmentor voltage. The possible chemical structures of the product ions were also examined using electronic structure calculations.
