Deciphering the anion dynamics in the fully deuterated pyridinium-based ionic liquid [C5Py][NTf2] via19F fast field cycling NMR relaxometry and MD simulation.
Fast field cycling (FFC) NMR relaxometry allows the investigation of molecular dynamics over a broad frequency range from 10 kHz up to 100 MHz. However, quantitative data interpretation is often limited by system-specific motional models and simplified assumptions for the analytical form of the relevant time correlatio...
