Cover Feature: 3D 14N/1H Double Quantum/1H Single Quantum Correlation Solid-State NMR for Probing the Parallel and Anti-Parallel Beta-Sheet Arrangement of Oligo-Peptides at Natural Abundance (ChemPhysChem 15/2018)

The Cover Feature illustrates a method to identify the β-sheet alignment through 3D 14N/1H double quantum (DQ)/1H single quantum (SQ) solid-state NMR at natural abundance. While the NH–NH correlation in 2D 1H DQ/1H SQ slices at 14N shift of NH does not appear in the parallel β-sheet alignment, the presence of NH–NH correlation identifies the anti-parallel alignment.
