Parameters obtained from Magnetic Resonance Spectra
Magnetic resonance spectra are generally recorded on a paper chart, changing conditions in the microwave circuits being converted to deflections from the base line in such a way that the extra power absorbed due to resonance is measured by the amplitude of the deflection. Ideally the chart moves past the pen at a rate linearly geared to the field, so that the intensity of the absorption is proportional to the area between the extrapolated base line and the curve, which has a Lorentzian or Gaussian shape, depending on the relaxation conditions in the sample (see Figure 4-1).
