Applications of long-lived nuclear states in magnetic resonance to the study of biomarkers, protein structure, imaging, and metabolomics are presented. Recently-invented molecular symmetry-based approaches for magnetic resonance have implications that are significant for molecular imaging via magnetic resonance, in vitro as well as in vivo, for quantum computing and for other fields. Spin states that are resilient to relaxation mechanisms became available in molecules of different sizes and structures, as experimental developments broadened the scope of symmetry-adapted spin states. The access to long molecular magnetisation relaxation times allows the study of free-radical triggered processes, of slow diffusion or of exchange within a time frame that was previously beyond reach.
