Infrared spectra of polypeptides were measured in the region of 1800-400 cm-1. For the a-helical form, disordered form, and antiparallel-chain &form, amide V bands arising from N-H out-of-plane bending modes were observed at 610-620, around 650, and 700-705 cm-1, respectively, and amide V' bands ari
## Abstract By analyzing the effect of urea and guanidine hydrochloride on the circular dichroism of many polypeptides and proteins, it is concluded that under conditions of high concentration of the perturbant and at low temperatures the resultant state approached is that of a local extended helix
