Fourier-transform infrared spectroscopy
Infrared light is irradiated on a surface, causing vibrations of molecular groups. The light thereby absorbed is characteristic for the molecular groups and spectra are used to analyze the chemical composition of a sample. We have the possibility of doing Fourier-transform infrared spectroscopy (FTIR) on entire surfaces and laterally resolved with FTIR microscopy, as well as analyzing in the NIR range.
