Comparison of spatially resolved constant current (CC) STM, constant height (CH) STM, AFM, and photon images, obtained by Au-CO-tips on a stable (top row) and a rotating ZnPc molecule (bottom row), adsorbed on trilayer NaCl on Au(111). All image sizes (including padding at the bottom AFM image) were 2.2 x 2.2 nm2. The constant current STM images were taken with 1 pA setpoint.
