摘要： 本文研究了鳞翅目昆虫性外激素——长链单不饱和脂肪醇乙酸脂系列化合物的红外和拉曼光谱。对主要谱带进行了归属。探讨了十一种系列化合物在室温液态和低温固态的光谱差异,得到了某些特征带与链结构的关系。结合其它物理性质,它们可用于估计同系物的双键位置和链长。

Abstract: The infrared and Raman spectra of the long chain mono-unsaturated fatty alcohol estersas insect sex pheromones of lepidoptera have been reported. The assignments of the vibra-tional frequencies of the compounds have been made. The spectral differences among to taleleven compounds at room temperature (liquid state) and lower than freezing point(solid state)temperature have been investigated. The relationships between some characte-ristic bands and the chain structures of the compounds have been obtained. Combining with some physical constants, these relationships can be used to estimate the double bond posi-tion and chain length of the compounds.

Key words: Mono-unsaturated alcohol ester, Infrared spectra, Rainan spectra, Sex pheromone
