Li nuclear magnetic resonance (NMR) spectroscopy is an ideal tool to study hierarchically assembled helicates of the form Li[LiLTi]. Internally bound and external lithium ions can be well distinguished by solution- or solid-state NMR spectroscopy and dimerization constants of the monomer/dimer equilibrium can be easily determined in solution. Averaged dimerization constants can be estimated in case of statistical mixtures of helicates formed from mixtures of ligands.
锂核磁共振（NMR）光谱是研究Li[LiLTi]形式的分层组装螺旋配合物的理想工具。通过溶液或固态NMR光谱可以很好地区分内结合和外锂离子，并且可以在溶液中轻松测定单体/二聚体平衡的二聚化常数。对于由配体混合物形成的螺旋配合物的统计混合物，可以估计平均二聚化常数。
