Abstract Measurements have been made of the longitudinal relaxation timeT 1 of31P for the individual resonances of the metabolites AMP, ADP, ATP, Pir and PCr (phosphocreatine) in H2O and D2O solutions from 5 to 60°C at various concentrations and at frequencies of 40 MHz (2.3 T) and 120 MHz (7 T). The contributions of dipolar, chemical shift anisotropy, and spin-rotation mechanisms have been separated, and activation parameters of the underlying molecular reorientations have been determined.
