Fig. 3. NCI plots of 5-O• radical for DMW (left), AUR (center) and FLC (right). Blue regions refer to strong attractive interactions, green regions refer to weak dispersion-based interactions, and red regions refer to repulsive interactions (isovalue = 0.7). (For interpretation of the references to colour in this figure legend, the reader is referred to the Web version of this article.)
