abstract = {We report a new contrast mechanism in which scanning
tunnelling micrographs of a certain class of molecules
resemble chemists' structure formulae. The method is based
on adding molecular hydrogen below its condensation
temperature to the tunnelling junction of a low-temperature
scanning tunnelling microscope. In the presence of hydrogen,
the scanning tunnelling microscope contrast can be switched
between the conventional mapping of the electronic local
density of states and the new geometric imaging by selecting
the appropriate bias voltage. Scanning tunnelling
spectroscopy suggests that the coupling of the electron
tunnelling current to an internal degree of freedom in the
tunnelling junction is responsible for the geometric
contrast. The new scanning tunnelling hydrogen microscopy
(STHM) allows the chemical identification of certain
molecular species by their structure.},
