    • 2O (without deuterium lock) with and without the amino acid guests present revealed an alteration of its very broad hydroxyl peaks, indicating that hydrogen bonding of the host plays a role in the assembly of the pseudorotaxanes. More details, however, could not be extracted from these spectra.
