Hole burning in polycrystalline C60: the final answer to the long pseudocoherent tails
Maria Belen Franzoni, Patricia R. Levstein, Jesus Raya +1
New NMR experiments reveal the origin of the "pseudocoherence" that leads to long tails in some Carr-Purcell-Meiboom-Gill (CPMG) sequences in contrast with the decay of a standard…
