The translational diffusion of the amphiphilic molecules in a number of lyotropic liquid crystalline phases has been measured with the pulsed NMR pulsed magnetic field gradient method. The amphiphiles studied were soaps, monoglycerids and lecithins. Measurements were performed both for oriented lamellar and for cubic phases. The order of magnitude of the diffusion coefficients was found to be the same as in neat liquids of analogous compounds. It was also found that the difussion coefficient depend markedly on the amphiphile end group in a way that parallels the area per polar head group as determined in X-ray studies. When corrections for geometrical factors has been made the diffusion rate is approximately equal in cubic and lamellar phases containing the same amphiphile.
采用脉冲核磁共振脉冲磁场梯度法测量了两亲分子在多种溶致液晶相中的平移扩散。所研究的两亲物为肥皂、甘油单酯和卵磷脂。对取向层状相和立方相都进行了测量。发现扩散系数的量级与类似化合物的纯液体中的量级相同。还发现，扩散系数明显取决于两亲物的端基，其方式与X射线研究中确定的每个极性头基团的面积相似。当对几何因素进行校正后，含有相同两亲物的立方相和层状相中的扩散速率大致相等。
