J Am Chem Soc. 2008 Sep 24;130(38):12582-3. doi: 10.1021/ja803601d. Epub 2008 Aug 26.


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