Terahertz spectroscopy, X‐ray diffraction, and solid‐state density functional theory were combined to accurately measure the elasticities of poly‐ l ‐proline helices by probing their spring‐like vibrational motions. In their Communication on page 6877 ff., T. M. Korter and co‐workers reveal that poly‐ l ‐proline is less rigid that commonly expected, and that the all‐ cis and all‐ trans helical forms exhibit significantly different Young's moduli.
