Quantitative infrared spectroscopy of ionic liquids
To make quantitative optical absorption measurements of ionic liquids. Quantitative spectroscopic measurements will allow for the development of optical diagnostics for in-situ testing of purity during synthesis, of impurities in battery applications due to breakdown of an ionic liquid, and of ionic liquid purity before use. In order to obtain quantitative spectroscopic measurements a FTIR spectrometer and thin-film cell are used. To accurately determine the thickness of the ionic liquid sample, the path length between the windows of the cell is calculated from etalon spectra before the cell is ...
