Query: An Experimental and Computational Study on Material Dispersion of
  1-Alkyl-3-Methylimidazolium Tetrafluoroborate Ionic Liquids   The material dispersion of the [Ckmim][BF4] (k = 2,3,4,6,7,8,10) family of
ionic liquids is measured at several temperatures over a broad spectral range
from 300 nm to 1550 nm. The experimental curves are fitted to a modified
three-resonance Sellmeier model to understand the effect of temperature and
alkyl chain length in the dispersion. From the parameters of the fitting, we
analyze the influence that the different constituents of these ionic liquids
have in the dispersion behaviour. In addition, a semi-empirical approach
combining simulated electronic polarizabilities and experimental densities for
predicting the material dispersion is successfully tested by direct comparison
with the experimental results. The limitations of this method are analyzed in
terms of the structure of the ionic liquids. The results of this work aim to
increase our knowledge about how the structure of an ionic liquid influences
its material dispersion. Understanding this influence is fundamental to produce
ionic liquids with tailored optical properties.
