What are the steps of magnetic resonance spectroscopy?

Magnetic resonance spectroscopy uses three primary steps for its procedure. The first step is to make sure the alignment (polarization) is correct, so that the magnetic nuclear spins in a constant, applied magnetic field (B0). In the second step, the nuclear spins are disturbed by a radio-frequency (RF) pulse. The third and final step is the analysis and detection of the electromagnetic waves released by the nuclei of the substance, due to the RF pulse.
