A form of two-dimensional (2D) vibrational spectroscopy was used to examine the structure of a cyclic penta-peptide (cyclo-Mamb-Abu-Arg-Gly-Asp) for which both the NMR and the x-ray structures are known. Spectrally resolved cross peaks occur in the off-diagonal region of the 2D IR spectrum, analogous to those of 2D NMR of proteins and peptides. The first results have been published (Proc. Natl. Acad. Sci. USA 96, 2036 (1999)).

使用二维 (2D) 振动光谱的形式 检查环状五肽的结构 （环-Mamb-Abu-Arg-Gly-Asp），NMR 和 X 射线 结构是已知的。 光谱分辨的交叉峰出现在 2D IR 光谱的非对角区域，类似于 2D 光谱 蛋白质和肽的 NMR。 第一批结果已经公布 （Proc. Natl. Acad. Sci. USA 96, 2036 (1999)）。
