This LEAI-16 Experimental System of Pulsed Nuclear Magnetic Resonance (Pulsed MNR) consists of pulse series generator, RF pulse generator, RF switching amplifier, detection probe, and magnet. It has features of convenient operations, high SNR, and remarkable teaching effect. It can measure both relaxation time and chemical shift, as well as processing data with software. It is an ideal experimental instrument for advanced physics laboratories.
Using this instrument, the following experiments can be conducted:
1.Learn the basic principle of pulsed nuclear magnetic resonance and its practical applications
2.Observe sample’s FID (free-induction-decay) signal, recognize the influence of magnetic field homogeneity to resonant signal
3.Observe spin-echo signal, measure the spin-lattice relaxation time T1
4.Measure the spin-spin relaxation time T2 using reversal recovery method and saturated recovery method
5.Measure the chemical shift of material Dimethylbenzene.
