What is the fine-grained topic of the following text: Herein, we show that through a combination of one-and two-dimensional, multinuclear solid-state NMR spectroscopy, chemical modelling, automated electron diffraction tomography, and an analysis based on X-ray pair distribution functions, it is finally possible to resolve the H/Li substructure. Only return the topic.
