Manipulation of phase and amplitude modulation of spin magnetization in magic angle spinning nuclear magnetic resonance in the presence of molecular diffusion
Head and Neck Neoplasms
The effects of diffusion on high resolution nuclear magnetic resonance (NMR) spectra of fluids in complex and porous media obtained in a spinning sample with simultaneous spin manipulation by a sequence of radio-frequency (RF) pulses were studied. By using TOSS, the unique differences due to molecular diffusion were determined. These differences carry the information about the dynamics of the molecular motion and the landscape.
