图4. RASA2DJ方法应用于具有小J偶合常数体系和复杂样品体系.左侧为溶于DMSO-d6的甲基丙烯酸丁酯的1D NMR谱和RASA2DJ谱，RASA2DJ的总采样时间为4 min；右侧为溶于DMSO-d6的雌二醇(部分区域)的1D NMR谱和RASA2DJ谱，RASA2DJ的总采样时间为5 min(根据文献[44]修改)

Fig.4. RASA2DJ experiments on small J coupling systems and complex samples. 1D NMR and RASA2DJ spectra of butyl methacrylate in DMSO-d6 are shown on the left. The total experimental time of RASA2DJ is 4 min. 1D NMR and RASA2DJ spectra of estradiol in DMSO-d6 (part region) are shown on the right. The total experimental time of RASA2DJ is 5 min (Reproduced from Ref. [44])
