## Abstract Depending on their environment, polyproline peptides form chiral helices that may be either leftβ (PPII) or rightβhanded (PPI). Here, we have characterized both the structure and free energy landscapes of Aceβ(Pro)~__n__~βNme (__n__ an integer less than 13) peptides, in vacuo and in imp
