Proton resonance for oscillating field of the order of static magnetic field
چکیده انگلیسی
A spin decoupling method in nuclear quadrupole resonance spin echo experiment is used to detect the proton magnetic resonance absorption spectrum. The behavior of proton resonance in α phase of polycrystalline p-dichlorobenzene as a function of the intensity of the proton decoupling oscillating field (H2) is measured. Good agreement between the experimental resonance frequency and Shirley's theory for a non-interacting 1/2 spin system is observed. To our knowledge this is the first time the NMR proton frequency dependence on linear polarized excitation field intensity for H2/Ho as high as 1.8 is measured.
