一、引言远在1800年,英国物理学家W.Herschel就发现了红外线(亦称“热线”)。然而,由于探测技术的落后,直到1892年才被用于有机基团的测定。随后,有许多红外光谱工作者积极从事这一研究工作。1905年Coblentz发表了128种有机化合物和无机化合物的红外吸收光谱,红外光谱与分子结构之间的特定联系才被确认,导致光谱学的 I. Introduction As far back as 1800, the British physicist W. Herschel discovered infrared (also known as “hotline”). However, it was not used for the determination of organic groups until 1892 due to the poor detection technology. Subsequently, many infrared spectroscopy workers actively engaged in this research work. In 1905, Coblentz published infrared absorption spectra of 128 organic compounds and inorganic compounds, and the specific connection between infrared spectra and molecular structures was confirmed, leading to spectroscopic
