Long-lived states involving a manifold of fluorine-19 spins in fluorinated aliphatic chains
{{output}}
Long-lived states (LLSs) have lifetimes T LLS that exceed longitudinal spin-lattice relaxation times T 1 . In this study, lifetimes T LLS (19F) have been measured in three different achiral per- and polyfluoroalkyl substances (PFAS) containing two or ... ...
