Description:About the Seminar:\n\nBattery development is a trial-and-error 
 process to develop more efficient energy storage. This is due to many diff
 erent factors contributing to suitable electrolyte solutions that are not 
 well understood at a molecular level. Ion transportation is the main role 
 of an electrolyte solution\, and as a scientific community\, we lack exper
 imental evidence to analyze the different modes of ion transport and the t
 imescales they occur. Structural and vehicular ion transportation are two 
 proposed mechanisms with both advantages and disadvantages. The paper I wi
 ll focus on (Dereka et al.\, JACS\, 144\, (19)\, 2022) uses different tech
 niques to analyze each mode’s contribution to ion transport. I will talk
  about two-dimensional infrared spectroscopy (2D IR) as it is an experimen
 tal technique to reveal the solvation structure and dynamics of many diffe
 rent systems. The issues arise with this technique as with many systems it
  is impossible to distinguish between vibrational energy transfer and chem
 ical exchange. This seminar will highlight this paper’s proposed method 
 of distinguishing these events using isotope labeling. This method is impo
 rtant to accurately indicate the different modes’ contribution to ion tr
 ansportation in these electrolyte solutions utilizing this technique. 4:00
