Applications of Floquet-Magnus expansion average Hamiltonian theory and Ferexpansion to study interactions in solid state NMR when irradiated with the magic-echosequence

摘要

This work presents the possibility of applying the Floquet-Magnus expansion and the Fer expansion approaches to the most useful interactions known in solid-state nuclear magnetic resonance using the magic-echo scheme. The results of the effective Hamiltonians of these theories and average Hamiltonian theory are presented.
