NMR hole burning in magnetic field gradient

The possibility to extend the optical hole-burning method to the NMR experiments performed in inhomogeneous magnetic fields was analyzed. The characteristic hole-burning response of the spin system is obtained by excitation of the sample with particularly radio frequency pulse sequence. The specific response of the spin system is sensitive to the molecular dynamics. Preliminary experiments were performed on pure water and demonstrates the possibility to obtain the hole-burning effect in strongly inhomogeneous magnetic fields.
