Abstract
High resolution 13C NMR spectra of solid poly(β-benzyl-l-aspartate) taking the right-handed α-helix, left-handed α-helix, ω-helix, and β-sheet conformations were recorded by the cross polarization-magic angle spinning method. 13C chemical shifts of the right-handed α-helix form were significantly displaced as compared with those of the left-handed α-helix and ω-helix forms.Keywords
