Abstract

Nuclear singlet states may have lifetimes that are much longer than the conventional relaxation time of nuclear spin magnetization. This review covers how these states may be generated, observed, and exploited in solution nuclear magnetic resonance (NMR). Potential applications include the study of slow molecular processes, the elucidation of molecular geometry, and the transport of hyperpolarized nuclear spin order.
