Left. 298 K CW-EPR spectrum (X-band) of an ABTS solution formed upon oxidation by T. versicolor laccase (black trace) overlapped with its best simulation (red trace). The experimental parameters are as follows: 0.1 G modulation amplitude, 0.2 mW microwave power, and ν = 9.86 GHz. The spectral parameters used for the simulation are given in Table 1. Right. B3LYP spin densities plot for the cation ABTS radical. The spin densities have been determined using a contour value of 0.003 with the program Molden [52]. Blue positive spin densities; red negative spin densities. Adapted from Brogioni et al. [47]
