Electron paramagnetic data for the characterisation of the radical formed upon reaction of nitrobenzene and multiple Lewis bases. The folder structure is as follows: Base ├── Concentration│ ├── Nitrobenzene_Base_molar_ratio │ │ ├── data.DSC│ │ ├── data.DTA│ │ ├── fit.DSC │ │ └── fit.DTA│ ├── Nitrobenzene_Base_Chelate_molar_ratio │ │ ├── data.DSC│ │ ├── data.DTA│ │ ├── fit.DSC │ │ └── fit.DTA Where Base is the employed Lewis base to run the experiment (tBuLi, LDA, NaiPrCp, LiOtBu, NaOtBu, KOtBu, LiHMDS, NaHMDS, KHMKDS)├──Concentration is the milliMolar concentration of nitrobenzene, │ ├── Nitrobenzene_Base_molar_ratio indicates the employed molar ratio between nitrobenzene and base, and │ ├── Nitrobenzene_Base_Chelate_molar_ratio, if present, indicates the employed molar ratio between nitrobenzene, base and a ligand (222 Cryptand, 15-Crown-5, 12-Crown-4) used to chelate the alkali metal.Inside each folder, the raw *.DSC and *.DTA Bruker files are given, and if available, their fit as well.The filenames contain the power attenuation (dB), modulation amplitude (Gauss) and number of scans used to record the data.
