This dataset includes neutron diffraction data from samples of indole in choline chloride:malic acid deep eutectic solvent in the presence and absence of water. The data has been processed using the program Gudrun to remove background scattering and instrumental effects, (creating .mint01 files) so it is ready for use in data fitting. The text files contain a header describing the name of the sample, the experimenters, and then three columns: Q (x-axis), differential scattering cross section (y-axis), error in intensity.
