Abstract

We theoretically analyzed Photoinduced force microscopy (PiFM) measurement on dimer molecules, using discrete dipole approximation. We obtained PiFM images of a dimer molecule for allowed and forbidden optical transitions. The PiFM images reflect the spatial structure of the localized electric field vectors. This study shows that PiFM provides multifaceted information based on the microscopic interaction between nanomaterials and light.
