Abstract. A theoretical framework is proposed to describe the spin dynamics driven by coherent spin mixing at Level Anti-Crossings (LACs). We briefly introduce the LAC concept and propose to describe the spin dynamics using a vector of populations of the diabatic eigenstates. In this description, each LAC gives rise to a pairwise redistribution of eigenstate populations, allowing one to construct the total evolution operator of the spin system. Additionally, we take into account that in the course of spin evolution a “rotation” of the eigenstate basis case take place. The approach is illustrated by a number of examples, dealing with magnetic field inversion, cross-polarization, singlet-state NMR and parahydrogen induced polarization.

Short summary
This work is discussing NMR experiments, which make use of coherent spin evolution at level-anti crossings. In this work, we provide a common description of such phenomena (hopefully, a reasonably simple one), which is illustrated by a number of examples from various subfields of NMR.
