Short summary
Long-lived nuclear spin order helps extend the timescale of polarisation storage. This occurs as populations of nuclear spin singlet states feature slow decays compared to longitudinal magnetisation. The excitation of these symmetry-adapted states required spin choreographies that were often overshadowed in scholarly presentations by their applications. We recapitulate some of the milestones achieved in designing methods for long-lived spin order excitation and comment on future perspectives.
