有机金属试剂的浓度可以通过获得纯试剂溶液的NMR光谱以及在第二个NMR管中获得纯参比溶剂的NMR光谱来方便地确定。在所有主要NMR软件中实现的PULCON关系然后用于基于光谱中的绝对积分、参考的已知浓度和积分下的质子数来计算试剂的浓度。
The concentration of organometal reagents can be conveniently determined by obtaining the NMR spectra of the neat reagent solution, and, in a second NMR tube, of a neat reference solvent. The PULCON relationship, implemented in all major NMR software, is then used to calculate the concentration of the reagent based on the absolute integrals in the spectra, the known concentration of the reference, and the number of protons under the integrals.
