Abstract

Measurements have been made of the longitudinal phosphorus-31 magnetic relaxation of phosphocreatine in H2O and D2O solutions from 278 to 333 K at 121.5 and at 40.5 MHz. The phosphorus-31 spin-lattice relaxation of phosphocreatine is dominated by intermolecular and intramolecular dipolar and chemical-shift anisotropy interactions. The relative contribution of the two interactions to the spin-lattice relaxation changes with NMR frequency. Activation energies characterizing the solution dynamics of the phosphocreatine molecule in H2O and D2O are 15.4±1.1 and 14.6±1.0 kJ/mol, respectively.
