Popis: The need for direct measurements of paramagnetic resonance absorption spectra in zero magnetic field is discussed. Two spectrometers have been built which together cover the range of 8 to 18 Gc/s; with one of these a spectrum is recorded over a range of nearly 6 Gc/s in a time of two minutes with a sensitivity sufficient to detect about 1017 Fe3+ ions at 80°K. Polycrystalline samples may be used, and examples are shown of the spectra of a dilute ferric chelate compound. A technique is described for obtaining the absorption line shape free from the effects of the associated anomalous dispersion.
