A normal coordinate analysis for cyclic tetra‐ L ‐alanine molecule is reported. A comparison of amide modes and other low‐frequency vibrations sensitive to conformational changes is made with those in poly‐ L ‐alanine. Intramolecular coupling coefficients are calculated using perturbation treatment.
