title: Cytosine derivatives form hemiprotonated dimers in solution and the gas phase.
abstract: Hemiprotonated dimers of cytosine derivatives, implicated in the formation of the i-motif of DNA, have been created in solution and the gas phase. The mechanism of dimerization has been analyzed by mass spectrometry and multidimensional NMR spectroscopy.
