结果表明，通过样品绕单轴旋转(变角旋转)或绕两轴旋转(切角旋转)，双晶向列型液晶相可以与外加磁场成任意角度的指向矢(垂直于双晶面)取向。这有望为双细胞和蛋白质的核磁共振研究开辟新的可能性，包括二维核磁共振实验中几种取向的关联。
It is shown that bicellar nematic liquid-crystalline phases can be oriented with the director (the normal to the bicellar plane) at an arbitrary angle to the applied magnetic field by sample rotation around one axis (variable-angle sample spinning) or around two axes successively (switched-angle spinning). This promises to open novel possibilities for NMR studies of bicelles and proteins incorporated into bicelles or dissolved in a solution containing bicelles, including the correlation of several orientations in a two-dimensional NMR experiment.
