摘要:
A theoretical treatment of the DREAM adiabatic homonuclear recoupling experiment is given using Floquet theory. An effective Hamiltonian is derived analytically and the time evolution of the density operator in the adiabatic limit is described. Shape cycles are proposed and characterized experimentally. Application to spin-pair filtering and as a mixing period in a 2D correlation experiment is explored and the experimental results are compared to theoretical predictions and exact numerical simulations.
