| 中文摘要 | the positive- and negative-ion electrospray ionization mass spectra of beta-cyclodextrin-amino acids complexes in nh4ac buffer have been reported in this paper. compared with positive-ion esi mass spectra of beta-cyclodextrin-amino acids complexes under the same condition, negative-ion mass spectra obtained for inclusion complexes of beta-cyclodextrin (cd) with tyrosine, phenylalanine and tryptophan, respectively, were completely dominated by deprotonated complex ions and [cd-h](-) ion which is the only daughter ion in collision-induced dissociation (cid) experiment of deprotonated complexes, the results indicated that the charged position for protonated and deprotonated complexes is different from each other. in addition, two complex ions for the same complex have similarly relative dissociation energies, which are higher than that of [cd+nh4](+), indicating that complexes observed in gasphase are not electrostatic adducts at all but complexes formed by hydrogen bonds. |
