“Elucidating the dynamics a nd structure of complex organic solutions by time resolved IR spectroscopy< /i>”
Complex organic s olutions are flourishing in the literature because of their applications in synthetic chemistry as well as their use as new designer solvents, electro lytes, etc. From a fundamental perspective, complex solutions remain challe nging to characterize because of their structural and dynamical heterogenei ty. Moreover, liquid solutions have short length-scales interactions with d ynamics on femtosecond to picosecond time-scales, which make them difficult to characterize with many conventional spectroscopies. In this talk, we pr esent our efforts to explore the structure and dynamics of complex organic solutions using FTIR and 2DIR spectroscopies as well as theoretical methods . In particular, the presentation will focus on describing both a “simple” organic solution composed of amides in chloroform and a complex organic sol ution: deep eutectic solvents (DES). In both cases, we explore the impact o f the molecular structure of the component on the solution dynamics and int eractions, where we find that trivial modifications to the solution compone nt carries drastic modifications to the solution molecular structure. This presentation will also discuss the implication of our findings on synthetic chemistry and extraction.

Moreover, liquid solutions have short length-s cales interactions with dynamics on femtosecond to picosecond time-scales, which make them difficult to characterize with many conventional spectrosco pies.

In particular, the presentation will focus on de scribing both a “simple” organic solution composed of amides in chloroform and a complex organic solution: deep eutectic solvents (DES). In both cases , we explore the impact of the molecular structure of the component on the solution dynamics and interactions, where we find that trivial modification s to the solution component carries drastic modifications to the solution m olecular structure.
