利用傅里叶变换拉曼光谱技术中的表面增强拉曼散射（Sers）技术，研究了生物脂肪族化合物的化学结构。的结构分析是通过测量的手风琴振动模式产生的有序，长的脂肪链。在减去背景光谱之后的Sers光谱给出了与通过质谱法研究的化学结构几乎完全一致的片段长度。Sers结果与质谱结果的一致性表明了长烃链中扭结的位置。Sers与质谱联用技术有助于探讨折叠的、长的生物脂质的结构。
The surface-enhanced Raman scattering (SERS) technique for Fourier transform Raman spectrometry is employed to reveal the chemical structure of biological aliphatic compounds consisting of folded, long aliphatic chains. The structural analysis is performed via the measurements of the accordion-vibration modes generated in the ordered, long aliphatic chain. The SERS spectra after subtraction of a background spectrum give segment lengths that are almost perfectly consistent with the chemical structures studied by mass spectrometry. The agreement of the SERS results with those of mass spectrometry suggests the positions of kinks in the long hydrocarbon chain. The combination technique of SERS and mass spectrometry is useful to discuss the structure of folded, long biological lipids.
