The Raman and infrared spectra of poly( L ‐lysine) and poly( DL ‐lysine) in solution are reported and the effects of various salts are investigated. The results demonstrate that α‐helix formation in solution is induced by specific salts and the spectral data support the hypothesis of regions of local order for poly( L ‐lysine) in aqueous solutions of low ionic strength.
