碳原子是组成有机分子的骨架,骨架中碳原子的排列次序确定后,整个分子的结构也就随之确定。因此~(13)C 核磁共振谱线的归属便具有重要的作用,出现了许多谱线归属的方法和技术。Vold 等人曾提出了部分弛豫傅里叶变换技术(简称 PRFT)。这一技术采用(180(?)-τ-
The carbon atoms are the skeletons of the organic molecules. After the order of the carbon atoms in the skeleton is determined, the structure of the whole molecule will also be determined. Therefore, the distribution of ~ (13) C nuclear magnetic resonance spectroscopy has an important role, and many methods and techniques for spectral attribution have appeared. Vold et al. Proposed a partial relaxation Fourier transform technique (PRFT). This technique uses (180 (?) -? -
