【摘要】 <正>长链烷烃与多种功能材料密切相关,如表面活性剂、生物膜、昆虫激素、储能材料等。链结构的变化对材料性能的影响引起了广泛的兴趣,弄清链结构变化与光谱之间的关系对探讨材料结构与性能的关系,异构体的鉴别有着重要的理论意义和实用价值。本文给储了(?)翅目昆虫性外激素--长链单不饱和脂肪醇乙酸酯系列化合物的红外光谱和拉曼光谱,该类化合物的结构通式为:更多还原

【Abstract】 The infrared and Raman spectra of long chain aono-unsaturnted fatty alcohol esters as an insect sex pheromones of lepidoplera have been reported.The assignaents of the vibrational frequencies of the compounds have been made.The spectral differences anong total eleven compounds in both rooa teaperature(liquid state) and lower than freezing point(solid state) temperature have been investigated.The relationships between some characteristic bands and the chain structures of the compounds have been obtained.Combining with soae physical constants,these relationships can be used to estiaate the double bond position and chain length.更多还原
