Abstract The IR and vibrational circular dichroism (VCD) spectra of a model two‐stranded β hairpin are compared to those of a related cyclic two‐stranded model, which are both stabilized by D Pro‐ 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 β sheet containing proteins. © 2002 Wiley Periodicals, Inc.
