The general theory of electron paramagnetic resonance (EPR) is discussed to present a background for the Bloch equations, hence explaining the phenomena of relaxation times in paramagnetic materials. Then, the details of construction of the pulsed superheterodyne EPR spectrometer are discussed in which the characteristics and functions of the components are specified. Procedures for its use in the measurement of T sub 1 are indicated and waveforms from various locations are presented to show the limitation of the pulsed EPR spectrometer that was constructed.
