引言部分弛豫福里哀变换核磁共振法(Part-ially relaxed FT-NMR)是一种特殊的核磁共振技术,使用此技术,分子或分子中各基团由于弛豫性质不同(弛豫时间T_1不同),在NMR 图谱中谱线或者向上或者向下,从而便于进行谱线归属。此方法于1968年由Vold 等人提出。此后,应用于消除溶剂峰和在~(13)C-NMR 谱中区分CH_3、CH_2、CH 和季碳。本文探讨此方法在高分子研究中的 INTRODUCTION Partial Relaxation Part-ially relaxed FT-NMR is a specific nuclear magnetic resonance technique in which each group in a molecule or molecule differs in relaxation properties (relaxation time T_1 is different ), The spectral line in the NMR spectrum either up or down, so as to facilitate spectral attribution. This method was proposed by Vold et al. In 1968. Thereafter, it was applied to eliminate the solvent peak and to distinguish CH 3, CH 2, CH and quaternary carbon in ~ (13) C-NMR spectra. This article explores this approach in polymer research
