Ultrafast vibrational spectroscopy (2D-IR) of CO2 in ionic liquids: Carbon capture from carbon dioxide’s point of view
Thomas Brinzer,Eric J. Berquist,Zhe Ren,Samrat Dutta,Clinton A. Johnson,Cullen S. Krisher,Daniel S. Lambrecht,Sean Garrett-Roe +7 more
TL;DR: The results suggest that the picosecond dynamics of CO2 are gated by local diffusion of anions and cations, and the observed structural relaxation timescales vary by up to an order of magnitude between ionic liquids.

Thiocyanate as a local probe of ultrafast structure and dynamics in imidazolium-based ionic liquids: water-induced heterogeneity and cation-induced ion pairing.
TL;DR: Results are consistent with a picture of thiocyanate as a local probe that can interrogate ultrafast structure and dynamics at a small spatial scale in ionic liquids.

Modeling Carbon Dioxide Vibrational Frequencies in Ionic Liquids: II. Spectroscopic Map
Clyde A. Daly,Eric J. Berquist,Thomas Brinzer,Sean Garrett-Roe,Daniel S. Lambrecht,Steven A. Corcelli +5 more
TL;DR: A spectroscopic map for the asymmetric stretch of CO2 in the 1-butyl-3-methylimidazolium hexafluorophosphate ([C4C1im][PF6]) ionic liquid (IL) is developed using DFT to compute the vibrational frequency of 500 statistically independent CO2 clusters extracted from an MD simulation.

Two-dimensional ultrafast vibrational spectroscopy of azides in ionic liquids reveals solute-specific solvation.
TL;DR: Two-dimensional ultrafast vibrational spectroscopy (2D-IR) shows that the picosecond dynamics of inorganic azides are substantially slower than organic azides in a series of homologous imidazolium ionic liquids, suggesting that neutral (organic) and charged (inorganic) azide are incorporated in the ionsic liquids with different solvation structures.

Modeling Carbon Dioxide Vibrational Frequencies in Ionic Liquids: III. Dynamics and Spectroscopy
TL;DR: The structure and dynamics of a model physisorbing ionic liquid, 1-butyl-3-methylimidazolium hexafluorophosphate, is investigated from the perspective of CO2 using two-dimensional (2D) IR spectroscopy and molecular dynamics simulations, revealing new insights into the interactions of a CO2 solute with the surrounding ionicLiquid.
