## Abstract Circular dichroism spectra for acidβsoluble calfskin collagen, gelatin, and poly(proline) II in solution have been extended into the vacuum ultraviolet region. The extended spectrum of gelatin reveals that the circular dichroism of this unordered polymer is more closely related to the s
## Abstract The positive circular dichroism band observed near 228 nm with poly(Lβproline) responds in a similar fashion to HCl and CaCl~2~. The spectra in the HCl solutions are compatible with a simple binding equation and a p__K__ near β2 for the dissociation of a proton from a protonated peptide
The infrared absorption of poly-L-proline in concentrated aqueous salt solutions was measured in the fundanierital region. Of primary interest were the carbonyl absorption of the peptide linkage and the methylene C-H bending absorption of the pyrrolidine ring. These spectral regions each show an add
