用~ 1H NMR研究了短链和中间链烷烃在硅纳米管中的取向有序性。测得的残余核偶极耦合表征分子有序度被发现依赖于孔径和分子长度在一个复杂的方式。从实验结果可以推断，所观察到的行为是由伴随的表面和分子间的相互作用，以及约束的效果。
Orientational ordering of short and intermediate -alkanes confined to silicon nanotubes has been studied using 1H NMR. The measured residual nuclear dipolar couplings characterizing the degree of molecular ordering were found to depend on the pore size and the molecular length in a complex way. It is inferred from the experimental results that the observed behavior is governed by concomitance of surface and intermolecular interactions as well as the effect of confinement.
