Coherence lifetimes in homonuclear dipolar decoupled 1
H solid-state NMR experiments are usually on
the order of a few ms. We discover an oscillation that limits the lifetime of the coherences by recording
spin-echo dephasing curves. We find that this oscillation can be removed by the application of a double
spin-echo experiment, leading to coherence lifetimes of more than 45 ms in adamantane and more that
22 ms in b-AspAla, corresponding to refocused linewidths of less than 7 and 14 Hz respectively.
