Detection of anisotropic hyperfine transitions in zero magnetic field using field-cycling techniques.
For the first time, we describe the detection of hyperfine transitions in zero magnetic field using field-cycling techniques and pulsed EPR spectroscopy. The sample investigated was coal, which shows an anisotropic electron spin-(13)C hyperfine interaction.
