Fig. 7. (a) Calculated ACID plots (contribution from π electrons only) of MC4-S (a) and its dication MC4-S2+ (b) in the singlet ground state. The magnetic field is perpendicular to the XY plane and points out through the paper. The blue and red arrows indicate the counter-clockwise (paramagnetic) and clockwise (diamagnetic) current flow, respectively. Calculated 2D-ICSS maps of MC4-S (c) and its dication MC4-S2+ (d). The top and bottom images are mapped at the XY and XZ planes, respectively.
