Tests of the length independence of helical propensities, wAla. (a) j = c = 1.0; (b) j = c = 0.0. Red dots correspond to experimental central Ala residue 13C═O chemical shifts for the length series of tL-Ala15-tL peptides at 2 °C. For each length n, lines correlate constant w values with calculated chemical shifts. The hypothesis of a length-independent wAla is falsified.
