Researchers use Raman spectroscopy and STM to allow chemical mapping of molecules to 1nm resolution

(Phys.org) —A team of researchers working at China's University of Science and Technology has succeeded in developing a chemical mapping technique capable of revealing the constituent atoms of a single molecule. In their paper published in the journal Nature, the team describes how they combined Raman spectroscopy with a scanning tunneling microscope (STM) to allow for chemical mapping of a molecule to a resolution of less than 1nm.
