💡 Novelty & Significance:
This study uniquely combines ultrafast IR spectroscopy, NMR, and MD simulations to reveal that ion cage escape time governs dynamics in ionic liquids. It establishes thiocyanate as an ideal anion surrogate and shows neutral solutes form mixed cages. The correlation between cage escape time and slow structural fluctuations provides a unified framework linking translational diffusion, orientational motion, and viscosity.
