Distinguishing gramicidin D conformers through two-dimensional infrared spectroscopy of vibrational excitons

Gramicidin D is a short peptide which dimerizes to form helical pores, adopting one of two conformations in the process. These conformations differ primarily in number of residues per turn and the hydrogen-bond registry between rungs of the helix. Using amide I 2D infrared (IR) and FTIR, we have dem...
