Queuing up : Molecular orientation within macroscopically aligned nanotubes of the peptide K can be studied by solid‐state NMR and IR spectroscopy. Line shape analysis of the NMR spectra indicates that the peptide NH bonds are tilted 65–70° relative to the nanotube long axis. Re‐evaluation of earlier X‐ray fiber diffraction data suggests that the peptide molecules are hydrogen‐bonded in a helical arrangement along the nanotube axis.
