Calibration curve of the L-band EPR line-width of LiNc-BuO versus pO2. LiNc-BuO crystals were suspended in PBS equilibrated with mixtures of oxygen/nitrogen gases of 21, 10, 5, 1, 0.5, and 0 % (in argon) oxygen. The spectra were measured under the following conditions: frequency, 1.2 GHz; incident microwave power, 1 mW; modulation frequency, 90 KHz; modulation amplitude, 0.02 mT; temperature, 35–38°C.
