19F[1H] NOE determinations in surface-coil experiments

Kinetics of heteronuclear cross-relaxation in dipolar coupled-spin systems: Applications toin vivo measurements

“…1.235 for 31 P-1 H and 1.984 for 13 C-1 H spin systems. Experimentally, the 31 P and 13 C signal gain observed in¨i¨o upon driving the proton spins in the tissue into saturation was always smaller than Ž .…”

“…the data with Eq. 66 yields a P-H cross- The N s 2 protons, which interact with one carbon nucleus, give rise to an intramolecular The rapid evolution of the 13 C nuclear polarization is a consequence of the strong interaction of carbon spins and directly bound protons. The truncated driven NOE of the methylene signal gives a 13 …”
