自20世纪80年代以来,随着超导磁体高磁场核磁共振仪的普及应用,二维核磁共振技术(2D-NMR)发展极快.应用二维核磁共振技术,为阐明和解析抗生素物质的化学结构,提供了新的途径,所以相关的报道已渐渐多了.作为抗生素研究工作者更关心的是二维核磁共振谱所提供的结构信息,所以本文拟结合抗生素结构研究的实例简要地介绍一些二维核磁共振技术的应用.二维核磁共振(2D-NMR)与常规的一维核磁共振的主要区别在于:一维核磁共振谱只涉及一个频率变量,是吸收峰强度对一个频率变量的作图.而二维核磁共振谱则代
Since the 1980s, with the popularization and application of high magnetic field nuclear magnetic resonance spectrometer of superconducting magnet, two-dimensional nuclear magnetic resonance technology (2D-NMR) has developed very fast.Using two-dimensional nuclear magnetic resonance technology, in order to elucidate and resolve the chemical Structure, provide a new way, so the related reports have gradually increased.As antibiotics research workers are more concerned about the structural information provided by two-dimensional nuclear magnetic resonance spectroscopy, so this article will be combined with examples of antibiotic structure of a brief introduction Two-dimensional nuclear magnetic resonance technology applications Two-dimensional nuclear magnetic resonance (2D-NMR) and conventional one-dimensional nuclear magnetic resonance of the main difference is: one-dimensional nuclear magnetic resonance spectrum involves only one frequency variable, is the absorption peak intensity of a frequency variable for Figure. The two-dimensional nuclear magnetic resonance spectrum generation
