我们获得了β-poly（L-alanine-ND）的光谱，在ND伸缩区发现了三个谱带。通过与聚甘氨酸I的氘代衍生物以及α-聚（L-丙氨酸-ND）的费米共振分析进行比较，我们得出结论，β多肽中涉及三能级费米共振，并且未受扰动的ND伸缩基频发生在2428 cm−1附近。
We have obtained the spectrum of β‐poly(L‐alanine‐ND), and find three bands in the ND stretching region. By comparison with Fermi resonance analyses of deuterated derivatives of polyglycine I as well as with α‐poly(L‐alanine‐ND), we conclude that a three‐level Fermi resonance is involved in the β polypeptide, and that the unperturbed ND stretch fundamental occurs near 2428 cm−1.
