Reference Spectra for the Ionic Liquids Employed in this Study

All ionic liquids were characterized using 1H NMR spectroscopy, IR spectroscopy and TOF SIMS. The spectra are shown below in the following order. For each ionic liquid the positive mass spectrum will be first, followed by the negative mass spectrum, and the IR spectrum. On the second page will be the 1H NMR spectra showing the proton shift. The ionic liquids are ordered alphabetically by acronym.
