This LEAI-15 Experimental System of Pulsed Nuclear Magnetic Resonance (Pulsed NMR) consists of pulse series generator, RF pulse generator, RF switching amplifier, detection probe, and magnet. It has features of convenient operations, high SNR, and notable teaching effect. It is an ideal experimental instrument for advanced physics laboratories.
Using this instrument, the following experiment contents can be performed:
1.Understand 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(option).
