Gas-phase versus liquid-phase structures by electrospray ionization mass spectrometry.
Preferred protonation: Does electrospray ionization mass spectrometry produce gas-phase or liquid-phase structures? The preferred protonation site in p-aminobenzoic acid depends upon the medium, and the structure of its conjugate acid varies with the solvent used during spraying.
