China Wholesale Electron Spin Resonance Factories – LADP-2 Experimental System of Pulsed NMR – Labor
China Wholesale Electron Spin Resonance Factories – LADP-2 Experimental System of Pulsed NMR – Labor Detail:
Experiments
1. Understand the basic physical theory and experimental configuration of a PNMR system. Learn to explain related physical phenomena in PNMR using classical vector model.
2. Learn to use signals of spin echo (SE) and free induction decay (FID) to measure T2 (spin-spin relaxation time). Analyze the influence of magnetic field homogeneity on NMR signal.
3. Learn to measure T1 (spin-lattice relaxation time) using reverse recovery.
4. Qualitatively understand the relaxation mechanism, observe the effect of paramagnetic ions on nuclear relaxation time.
5. Measure T2 of copper sulfate solution at different concentrations. Determine the relationship of T2 with the change of concentration.
6. Measure the relative chemical displacement of the sample.
