Abstract
An NMR spectroscopy using broadband spin-locking capable of efficiently observing nuclear Overhauser effects. A 90.degree. pulse is applied to create transverse magnetization. Then, an r.f. magnetic field is applied to lock the transverse magnetization. Prior to the spin-locking, a pulse is applied to align the magnetization with the spin-locking r.f. magnetic field. Subsequent to the spin-locking, another pulse is applied to reorient the magnetization in its original direction.
