(A) EPR spectrum observed during 5 min of irradiation of RB (20 μM) in the absence of TBBPA in phosphate buffer (pH 7). (B) EPR spectrum observed during the irradiation of RB (20 μM) in the presence of TBBPA (1 mM) in phosphate buffer (pH 7). (C) Simulation spectrum of B with an hfc of a2H = 2.36 G, and g-value of 2.0056. (D) same as B in the presence of sodium azide (20 mM).
