Figure 2

(a) Schematics showing the tip trajectory of STML measurements with the definition of the position for r=0 at the edge of the ZnPc molecule. (b) A series of experimental STML spectra along the line trace in (a) (−2.5 V, 200 pA, 20 s) with a lateral separation distance from r=0 to r=3.2 nm. (c) Enlarged spectra of (b) highlighting the dip shift (δωdip) for r=0 to r=2 nm. (d) Variation of the normalized dip depth (Dnorm) and dip shift (δωdip) with lateral separation distances. (e) Simulated spectra showing the coupling strength (g). (f) Enlarged spectra of (e) highlighting the dip shift.
