Using a white-light near-field scanning optical microscope (NSOM) we demonstrate near-field imaging and local plasmon spectroscopy of flat gold nanoparticles (FGNPs). These nanoparticles are atomically-flat single crystal plates with well defined shapes ranging from equilateral triangles to regular hexagons, which include intermediate truncated triangle shapes. NSOM images reveal the FGNP plasmon mode structure and its dependence on FGNP size and shape. Moreover, spatially resolved spectroscopy shows position dependent coupling to different plasmon modes.
