Continuous wave EPR spectra of SDH forms. Trace 1, SDHH57A at pH 5.8; trace 2, SDHR55M at pH 7.0. Experimental conditions were as follows: νmw = 9.444 GHz; modulation amplitude = 0.1 millitesla; microwave power = 0.2 milliwatt; temperature = 77 K. The narrow line at g = 2.0036 is the signal of the DPPH standard.
