PMID: 19102544
J Chem Phys. 2008 Dec 21;129(23):234513. doi: 10.1063/1.3040272.

A theoretical approach to the description of longitudinal (T(1)) relaxation in scalar coupled systems of spin 1/2 nuclei at arbitrary magnetic field is developed, which is based on the Redfield theory. The consideration is addressed to field-cycling relaxometry experiments...
