基于NMR的方法已经开发出用于快速表征分子的平移扩散。与获取一系列2D（13）C和（1）H谱的传统方法不同，所提出的方法涉及单个2D NMR谱，其可以在几分钟内获得。使用这种方法，它是可能的，以检测在溶液中的二苯丙氨酸的中间低聚物的存在下，在其自组装形成纳米管结构的过程中。
An NMR-based approach for rapid characterization of translational diffusion of molecules has been developed. Unlike the conventional method of acquiring a series of 2D (13)C and (1)H spectra, the proposed approach involves a single 2D NMR spectrum, which can be acquired in minutes. Using this method, it was possible to detect the presence of intermediate oligomeric species of diphenylalanine in solution during the process of its self-assembly to form nanotubular structures.
