Raw and processed PDF, XRD, electrochemistry, ssNMR data and CIF files along with corresponding metadata for all measurements published in the paper "Investigating Sodium Storage Mechanisms in Tin Anodes: A Combined Pair Distribution Function Analysis, Density Functional Theory and Solid-State NMR Approach." Specifically, we provide PDF data as .hdf5 or .tif (raw unprocessed) and .csv (integrated and extracted) files, XRD data as .tif (raw unprocessed) and .csv (integrated and extracted) files, electrochemistry data as .csv (plain text) files, and unprocessed NMR data in the IUPAC standard JCAMP-DX format, processed data available as .csv. We refer the reader to the aforementioned paper for further details.
