Abstract

Measurements have been made of the longitudinal phosphorus-31 magnetic relaxation of the individual phosphorus resonances of AMP, ADP and ATP at 121.5 MHz from 278 to 333 K and at 40.5 MHz at room temperature in H2O solutions of the chemicals. The phosphorus-31 spin-lattice relaxation times of all compounds are dominated by dipolar interactions and influenced by chemical shift anisotropy interactions to a different extent at the two frequencies. Phosphate group motion superimposed on the tumbling of the molecules is the main source of phosphorus-31 spin-lattice relaxation. Activation energies characterizing the combined motion range between 17.1 and 20.0 kJ/mol.
