Signal interferences from turbulent spin dynamics in solution nuclear magnetic resonance spectroscopy
The signal interference from turbulent spin dynamics in solution nuclear magnetic resonance spectroscopy was discussed. The unexpected dynamics, triggered by the joint action of the radiation damping and the distant dipolar field deteriorates the performances of the certain pulse sequences incorporating weak pulsed field gradients and long evolution times. The effects were demonstrated in three general classes of gradient NMR applications including solvent signal suppression, diffusion measurements, and coherence pathway selection.
