Datenpaket: Data and analysis scripts for: Large-Volume Low-Speed MAS NMR in High-Field Horizontal-Bore Systems Facilitated by 3D-Printing

Research data and analysis scripts supporting the manuscript "Large-Volume Low-Speed MAS NMR in High-Field Horizontal-Bore Systems Facilitated by 3D-Printing." The package contains the raw 79Br (KBr) and 1H MAS NMR datasets underlying the probe-head characterisation and the preliminary MAS demonstration, together with the Python scripts used to process them and generate the figures; and the rotor spinning-performance data from the parametric-optimisation studies (number of blades, blade angle, rotor-stator clearance, and wall thickness / sample volume), together with photographs of the 3D-printed rotor variants. CAD models, STL files, slicer profiles and the tuning/matching PCB layouts are available from the authors on request.

This dataset accompanies the manuscript "Large-Volume Low-Speed MAS NMR in High-Field Horizontal-Bore Systems Facilitated by 3D-Printing." Contents: (1) "NMR raw files/" — raw 79Br (KBr magic-angle setting) and 1H MAS NMR datasets plus spinning-frequency logs; (2) "nmr_processing/" — Python scripts (process_nmr.py, sidebands.py, etc.) that process the raw NMR data and generate the figures, with their outputs; (3) rotor spinning-performance spreadsheets, one file per design variant, for blade number ("Variation of Blades_"), rotor-stator clearance ("Variation of Diameter_"), blade angle ("Variation of Blade angle_") and wall thickness / sample volume ("Variation of Volume_"), plus combined "_ELN" workbooks; (4) photographs (.png) of the 3D-printed rotor variants. In the spreadsheets, columns give the measured spinning frequency versus driving gas pressure at the bearing gas pressures indicated; values are the mean of three nominally identical printed rotors.
