Abstract. Quantum mechanics and mathematical tools have played a pivotal role in the development of modern NMR spectroscopy. After an overview of NMR spectroscopy, recent advances in high-resolution solid-state NMR spectroscopy of quadrupolar nuclei will be presented as an example demonstrating the roles of quantum mechanics and mathematics. The technical development deals with the effect of nuclear quadrupolar spin interactions to solid state NMR spectra. Using perturbation theory, various orders of quadrupolar effect are expanded in irreducible representations that have well-characterized rotational properties. By single or double axial sample rotation and two-dimensional spectroscopy, quadrupolar effects up to the third-order can be experimentally averaged achieving high-resolution solid-state NMR spectra for applications in chemistry and material sciences.
