Abstract
The structure of the Gly-Pro and Pro-Gly dipeptides have been studied by laser ablation chirped pulse and molecular beam Fourier transform microwave (LA-CP-FTMW and LA-MB-FTMW) spectroscopy.\footnote{Bermúdez, C.; Mata, S.; Cabezas, C.; Alonso, J. L., Tautomerism in Neutral Histidine. Angew. Chem. Int. Ed. 53, 11015–11018 (2014).}$^{,}$\footnote{J. L. Alonso and J. C. López, in Gas-Phase IR Spectroscopy and Structure of Biological Molecules, eds. A. M. Rijs and J. Oomens, Topics in., 2015, vol. 364, pp. 335–402.} While three conformers of Gly-Pro have been characterized only one conformer has been found in Pro-Gly. Interestingly, the resemblance of the structure determined in Gly-Pro and that observed in the crystal of a collagen-like peptide is striking.
