现代分析测试技术在印染行业的应用(十九)——核磁共振波谱分析技术及其在纺织材料和染化料剖析中的应用

Application of modern analytical testing techniques to dyeing and finishing industry(XIX)——Identification of textile material and dyes and chemicals by nuclear magnetic resonance spectroscopy

介绍了核磁共振波谱(NMR)分析技术的基本原理(包括原子核的磁性质、自旋核的进动和共振、弛豫、化学位移、偶合裂分等概念)、发展历程,以及该技术在纺织材料、染料、纺织助剂和表面活性剂剖析中的应用。

Ultraviolet spectrum, infrared spectrum, mass spectrum and nuclear magnetic resonance spectrum are the most popular and effective techniques for analyzing structures of organic substances. This paper introduced the basic principle （ including magnetic properties of atomic nuclear, resonance of spin nuclear, relaxation, chemical displacement and coupling fission）, developing history, as well as application to identify textile material and dyeing chemicals of nuclear magnetic resonance spectroscopy.
