核磁共振信号与样品浓度关系的实验研究

Experimental study of the relationship between NMR signal and sample concentration

通过核磁共振实验研究了硫酸铜水溶液的浓度对核磁共振信号的影响,实验测定了核磁共振信号随硫酸铜水溶液浓度的变化.结果表明,当硫酸铜水溶液浓度为0.1%时,核磁共振信号最强且波形最好.对实验结果进行了分析总结和理论解释,得出的结论对实验教学具有一定的参考价值.

It was studied the concentration of copper sulfate aqueous solution effect on the NMR signal through the nuclear magnetic resonance experiment.The nuclear magnetic resonance signal variation with the concentration of the copper sulfate aqueous solution is measured.The results show that when the copper sulfate aqueous solution concentration is 0.1%,the nuclear magnetic resonance signal is the strongest and the waveform is the best.Finally,the experimental results are analyzed and theoretically explained.This experimental conclusion has a great reference value for experimental teaching.
