In the development of new polymer materials with novel properties, quick and trustworthy analysis is essential. FTIR and Raman spectroscopy and microscopy can address this need: FTIR spectroscopy is able to identify chemical structures and functional groups within polymers, providing detailed information about the molecular composition and chemical bonds by measuring the absorption of infrared light at various wavelengths. Raman microscopy, on the other hand, complements FTIR by using inelastic scattering of monochromatic light (from a laser source) to obtain vibrational, rotational, and other low-frequency modes. For polymer samples, these techniques can help to characterize crystalline structures, analyze the distribution of different polymer components, determine density or the level of curing, and more.
