The long-lived nuclear singlet state of N-15-nitrous oxide in solution
A N-15 nuclear singlet lifetime of over 26 min has been observed in a solution of (N2O)-N-15, by using a field-cycling NMR pulse sequence. This observation suggests applications of hyperpolarized (N2O)-N-15 in medical imaging and for flow and diffusion studies.
