A Bruker 300 MHz spectrometer was used to measure 1H NMR spectra. Approximately 6 mg of each sample was digested in 0.7 mL of a stock solution of DCl (20%)/D2O (0.889 mL) and DMSO-d6 (3 mL). Data analysis was performed in TopSpin software. Predicted 1H NMR spectra of decomposed IL structures was generated using www.nmrdb.org after drawing the corresponding chemical structure of decomposed EMIM cations67,68.
