Some comment is needed about what could be meant by" high-field" ESR. In colloquial use scientists usually mean high-frequency when the say high-field, and refer to ESR frequency greater than that commonly used or commercially available. In this sense, high-field ESR has meant the use of frequencies above 35 GHz (called Q-bandª by most ESR spectroscopists). Now that 95 GHz spectrometers are commercially available from Bruker Instruments, and frequencies of 95, 150, and 250 GHz are offered by Resonance Technologies, this common definition moves the lower bound to higher frequencies. Nevertheless, until these commercially available frequencies become commonly used, most spectroscopists will continue to consider them" high" frequencies. The assumption is that we also refer to the magnetic field for g= 2, so high frequency implies high magnetic field. In this review frequencies above 90 GHz are defined as" high." To achieve resonance at g= 2 at these frequencies requires magnetic fields greater than 3.2 T.
