Abstract:Infrared (IR) vibrational spectroscopy is one of the oldest and the most widely used analytical tool for the characterization of chemical species in samples. Spatially resolved IR spectroscopy, the IR spectro‐microscopy, may offer information on the spatial arrangement of chemical species on sample surfaces as well as the chemical identity of the species. However, conventional far‐field IR microscopy offers spatial resolution of 5 μm, which is not nearly enough for fully characterizing the sample structures in… Show more
