Multispin dynamics of the solid-state NMR free induction decay
Multispin dynamics of the solid-state NMR free induction decay
We present a new experimental investigation of the NMR free induction decay (FID) in a lattice of spin-$1∕2$ nuclei in a strong Zeeman field. Following a $\ensuremath{\pi}∕2$ pulse, evolution under the secular dipolar Hamiltonian preserves the coherence number in the Zeeman eigenbasis, but changes the number of correlated spins in …
