The IR and vibrational circular dichroism (VCD) spectra of a model two-stranded beta hairpin are compared to those of a related cyclic two-stranded model, which are both stabilized by DPro- Gly turns. The spectra are compared to ab initio based simulations to support specific assignments of the dominant features and suggest a revised interpretation of the IR and VCD spectra for beta sheet containing proteins.
