Long-lived nuclear singlet order in near-equivalent 13c spin pairs
Molecules that support 13C singlet states with lifetimes of over 10 min in solution have been designed and synthesized. The 13C2 spin pairs in the asymmetric alkyne derivatives are close to magnetic equivalence, so the 13C long-lived singlet states are stable in high magnetic field and do not requir...
