Reaction Enthalpies for M+L = M+ + L, Where M+ = Na+ and K+ and L = Acetamide, N-Methylacetamide, N,N-Dimethylacetamide, Glycine, and Glycylglycine, from Determinations of the Collision-Induced Dissociation Thresholds
摘要:
With electrospray (ES), ions present in solution can be transferred to the gas phase. The method provides unique opportunities for studies of hitherto inaccessible ions. Collision-induced dissociation threshold measurements of gas phase ions produced by ES are described. The thresholds for the reactions M(+)L = M(+) + L, where M(+) is Na+ or K+ and L is acetone, dimethyl sulfoxide, acetamide, N-methylacetamide, N,N-dimethylacetamide, glycine, glycinamide, succinamide, and glycylglycine, were determined. Enthalpy changes for the reaction were derived from these data.
