In the following work, we use the prototypical system of tin phthalocyanine (SnPc) on Au(111) to investigate the feasibility of a DM automated classifier and compare it to ML methods. This molecular system has the advantage that the SnPc adsorbs on the

SnPc acts very similarly to CuPc, except the aforementioned F-LUMO is not completely depleted but remains partially filled

To fill this gap in knowledge, here, we report room-temperature (RT) and low-temperature (LT) STM-based studies of the adsorption of nonplanar tin phthalocyanine (SnPc) molecules a rutile (110)-1 × 1 surface of TiO2. SnPc molecules appear on such a surface in two flat-lying geometries defined by
