摘要
α-氰基丙烯酸乙酯是一种被广泛应用的粘合剂,俗称502胶,近年来它开始被用于指纹化学提取方面,作为指纹上残留物的背底,它的拉曼光谱分析变得更加重要。之前的报道只对其一部分的拉曼振动模式有比较粗略的指认。本文从实验中得到固化后的α-氰基丙烯酸乙酯的拉曼光谱,将其与丙烯酸、乙基化合物、氰基化合物等已经有详细、成熟指认的有机物的拉曼振动模式进行对比,同时考虑到α-氰基丙烯酸乙酯发生聚合反应的特有形式,对其有拉曼活性的20个振动模式进行了一次细致地指认。
Abstract
Ethyl α-cyanoacrylate is a widely used adhesive,which is commonly known as superglue.In recent years,it was also being used as a background for detect the exogenous substances present in latent fingerpints by Raman measurement.Only half of the Raman modes have been assigned in earlier paper,and the assignment is not very accurate.The Raman spectrum of ethyl α-cyanoacrylate which is used in this article was obtained from experiment.Compare with the well-assigned organic compound such as acrylic acid,compound with ethyl group,and compound with cyan group,and considering the polymerization of the ethyl α-cyanoacrylat monomers,the 20 Raman active modes of ethyl α-cyanoacrylate have been assigned elaborately.
