因此准确地表达1H NMR化学位移值数据就十分地重要。所有氢谱信号可分为单重峰s(缩写自singlet)与多重峰两大类, 多重峰又进一步划分为有规则多重峰(见下段)与不规则多重峰m两次大类(subclass 4、ification)。前者更进一步划分为有规则简单多重峰(simple multiplet7)与有规则组合多重峰(compound peak, 见下段)...

With these three chemometric methods, the metabolic responses of yeast at four starving conditions have been characterized (summarized in Table 1). Finally, we used all this information to interpret the observed variations in a biochemical context. Chemometric analysis of the complete 1H NMR ...
Quantification of metabolites was conducted using ChenomX NMR Suite 8.6. after matching the shape and position of a compound signature in the software to the shape of our spectrum (peak-based fit style). Compound concentrations were measured by determining the height of each compound signature that...
