WebOct 25, 2007 · The longitudinal relaxation time of ortho-hydrogen (the spin isomer directly observable by NMR) has been measured in various organic solvents as a function of temperature. Experimental data are perfectly interpreted by postulating two mechanisms, namely intramolecular dipolar interaction and spin-rotation, with activation energies … WebThe relaxation times T 1 and T 2 were 0.9 s in the first hydration layer and approached bulk water relaxation times further away from the peptide. In the analysis restricted to the first hydration layer, the simulated correlation times of the intramolecular dipole–dipole couplings varied from τ 1 ′ = 39.3 ps to τ 2 ′ = 150 ps ( Table 1 ), reflecting significant …
