摘要

In this review,we present a brief overview on the recent advances in ?ngstr?m-resolved tip-enhanced Raman spectromi-croscopy.We first introduce the theoretical understanding of the confinement of light at the atom-istic scale,and explain how the Raman scattering from a single molecule happens under the"il-lumination"of such an atomi-cally confined light.Then we describe the latest developments on ?ngstr?m-resolved tip-enhanced Raman spectromicroscopy,particularly on a new methodology called"scanning Raman picoscopy"for visually constructing the chemical structure of a single molecule in real space.Finally,we give a perspective of this technique in various applications where identifying the chemical structures of materials at the chemical bond level is required.
