| Popis: | Coherent superpositions between nuclear singlet and triplet spin states of pairs of J-coupled nuclei in high magnetic fields can be excited and sustained by oscillating radio-frequency (rf) radiation. The relaxation time constants of these ‘long-lived coherences’ can be up to nine times longer than those of allowed single-quantum coherences. We detail herein the development and early applications of long-lived coherences. |
