利用分子间双量子技术，在非均匀磁场中获得高分辨的核磁共振谱。该方法利用溶剂和溶质核自旋之间的远偶极相互作用。化学位移，J耦合，多重性模式，和相对面积保留的方法。除了J耦合的标度因子有1.5倍的变化外，其他参数与从均匀场中获得的一维谱中提取的参数一致。
Intermolecular double-quantum technique is used to yield high-resolution NMR spectra in inhomogeneous magnetic fields. The method exploits the distant dipolar interactions between the solvent and solute nuclear spins. Chemical shifts,Jcouplings, multiplicity patterns, and relative areas are retained with the method. Except for a 1.5-fold change in the scale factor ofJcouplings, other parameters are consistent with those extracted from one-dimensional spectra obtained in a homogeneous field.
