摘要：

A dynamic frequency shift for spin 1/2 systems is described, which originates from dipolar and chemical shielding anisotropy cross-correlation, and which is manifested as an additive contribution to the apparent scalar J coupling constant. Its characteristic dependence on molecular motion and magnetic field strength may serve as a complementary source of dynamic information.
