Atomic force microscopy (AFM) with functionalized tips achieves atomic and bond-resolved resolution providing insights into structure , charge states , charge distribution , and bond-order relations  of individual molecules. By atom manipulation elusive molecules can be created. Recently, we generated the elusive carbon allotrope cyclocarbon and resolved its debated structure . On insulating substrates, charge-state control enables the characterization or aromaticity and structure of single molecules in different oxidation states , measurement of the reorganization energy  and excited state spectroscopy .
