Proton nuclear magnetic resonance spectroscopy ((1)H NMR), which has become an important tool for the study "in situ" of beta-cyclodextrin (beta-CD) complexes, was used to study and structurally characterize the inclusion complexes formed between beta-CD and isoproturon, fenuron, monuron and diuron. The high variation of the chemical shifts from the proton located inside the cavity (H-3, H-5 and H-6) coupled with the non variation of the one located outer sphere of the beta-CD (H-1, H-2 and H-4) provided clear evidence of the inclusion phenomena. Two-dimensional rotating frame Overhauser effect spectroscopy (ROESY) experiments were carried out to further support the proposed inclusion mode.
质子核磁共振波谱法（¹H NMR）已成为研究β-环糊精（β-CD）配合物“原位”情况的重要工具，用于研究β-CD与异丙隆、非草隆、灭草隆和敌草隆形成的包合物，并对其进行结构表征。位于空腔内的质子（H-3、H-5和H-6）化学位移变化很大，而位于β-CD外球的质子（H-1、H-2和H-4）化学位移不变，这为包合现象提供了明确证据。进行了二维旋转框架奥弗豪泽效应光谱（ROESY）实验，以进一步支持所提出的包合模式。
