The calculated ESFs, in kcal/mol, of the peptide groups in two helical alanine peptides are plotted against residue number. The peptides contain either five or 15 alanine residues, plus N-terminal acetyl and C-terminal N-methylamide blocking groups. The backbone φ,ψ angles are −65° and −40° respectively. For other information, see legend to Fig. 1.
