In liquids, rapid isotropic motions of the nuclei average out the anisotropic interactions effectively to zero, whereas in the case of solids, these interactions are not averaged out [ 11 - 17 ].

The technique of NMR spectroscopy deals with time-dependent proportions of nuclear spin systems and it is imperative to solve the time-dependent Schrodinger equation in order to understand and predict the spin system dynamics. Solving time-dependent linear differential equations is a central problem in quantum physics in general and solid-state NMR [ 18 ].

Several theories have been developed and introduced to solid-state NMR. The first AHT explains how periodic pulse sequence can be used to switch off or transform the symmetry of selected interactions in coupled, many spin systems allowing NMR spectroscopists to create effective spin Hamiltonians with a wide variety of intriguing and useful properties [ 24 - 37 ].

The Floquet theory has proven to be a powerful tool for the spin system under periodical time-dependent Hamiltonians such as solid samples undergoing mechanical rotations at the magic-angle, or solution samples subjected to cyclic RF irradiation.

This approach FLT has the advantage of describing the spin dynamics at all times and it is not limited to a single time-dependent perturbation, but valid for cases subjected to interactions with multiple time periodicities [ 38 - 61 ].

The ultimate goal of this review paper is deliberately to downplay the evolution of theories used in solid-state nuclear magnetic resonance, from the milestone theories including the AHT and the FLT to the most recent theories such as the Floquet Magnus expansion FME [ 18 ] and the Fer expansion FE [ 62 , 63 ].

This approach is still in its infancy and was illustrated in NMR by considering simple applications such as the calculation of Bloch-Siegert shift in NMR and the analyzing of the heteronuclear decoupling in solid-state NMR [ 62 ]. This paper discusses major milestones theories including average Hamiltonian theory and the Floquet theory.

Next emerging theories, including Fer expansion and Floquet-Magnus expansion, are covered. Various illustrative applications highlighting the potential of these theories in analyzing a variety of solid-state NMR experimental methods are presented.

Our conclusions present the propagators and discuss the convergence aspects of the theories therein. Milestones Theories II.

Average Hamiltonian Theory An important landmark to describe the effect of time-dependent interactions and the accompanying improvements was the introduction of average Hamiltonian theory AHT in NMR. Developed by John Waugh and co-workers in , the AHT approach became the main tool to study the dynamics of spin systems subject to an RF perturbation.

This approach is the most commonly used method to treat theoretical problems in solid-state NMR and have been used sometimes casually [ 68 ]. The AHT explains the average motion of the spin system, the effects of multiple-pulse sequences, and the effects of a time-dependent perturbation applied to the system.

This is satisfied only if H t is periodic T and the observation is stroboscopic and synchronized with period T. Two major expansions Baker-Cambell-Hausdorff and Magnus and an exact computation including the diagonalization of the time evolution operator defined the average Hamiltonian [ 26 , 44 ].

This technique has been widely used in the NMR literature in the development of multiple pulse sequences and in the context of both decoupling and recoupling experiments. The AHT set the stage for stroboscopic manipulations of spins and spin interactions by radio-frequency pulses and also explains how periodic pulses can be used to transform the symmetry of selected interactions in coupled, many-spin systems considering the average or effective Hamiltonian of the RF pulse train.The carbon T1 results observed in Powhatan No.
