Characterizing chemical reactions at a single-molecule scale enables a deep understanding of the mechanism of complex chemical reactions and thus establishes new material science frameworks. Previous works explore the real-time current changes of reactants and its products to figure out the steps of the reaction process. However, it is hard to identify the paths of some reactions accurately because the current signal does not have fingerprint information of the reactants. Tip-enhanced Raman spectroscopy (TERS) can accurately characterize chemical reactions due to its ability to characterize chemical bond fingerprint information at single-molecule scale precision. By combining Raman spectroscopy with single-molecule Break Junction technology, we can control single-molecule reactions through electric fields and simultaneously observe the Raman shifts of its corresponding chemical bonds.
