      abstract = {Water is a critical component in polyelectrolyte anion  exchange membranes (AEMs). It plays a central role in ion  transport in electrochemical systems. Gaining a better  understanding of molecular transport and conductivity in  AEMs has been challenged by the lack of a general  methodology capable of capturing and connecting water  dynamics, water structure, and ionic transport over time  and length scales ranging from those associated with  individual bond vibrations and molecular reorientations to  those pertaining to macroscopic AEM performance. In this  work, we use two-dimensional infrared spectroscopy and  semiclassical simulations to examine how water molecules  are arranged into successive solvation shells, and we  explain how that structure influences the dynamics of  bromide ion transport processes in polynorbornene-based  materials. We find that the transition to the faster  transport mechanism occurs when the reorientation of water  molecules in the second solvation shell is fast, allowing a  robust hydrogen bond network to form. Our findings provide  molecular-level insights into AEMs with inherent transport  of halide ions, and help pave the way towards a  comprehensive understanding of hydroxide ion transport in  AEMs.},
