We demonstrate a high correlation between the natural logarithms of the relative intensities of protonated molecules of amino acids by electrospray and their standard hydration free energies (r=0.98). This result means that the solvation free energy is an important physical parameter for interpreting the difference in protonated molecule intensities by electrospray.
