Nuclear Magnetic Resonance Spectroscopy:

The basic arrangement of NMR spectrometer is shown in Figure 35.04. The sample is positioned in the applied magnetic field using electromagnet and microwaves are used in the radio frequency input circuit to excite the sample and to induce transitions between different nuclear spin states. This induces a radio signal in the output circuit, which generates an output signal.
