WebRaman spectroscopy is a valuable tool for probing chemical composition. It is widely applied in chemical analysis of molecular species and structures of chemical bonds (1, 2), and is therefore widely extended to the fields of biomedical imaging (e.g., refs.3–5), material science (e.g., ref. 6), and remote sensing (e.g., ref. 7).Comparing with other molecular … WebBased on the Raman spectra, polystyrene (PS), polyethylene terephthalate (PET), polyethylene (PE), and polypropylene (PP) are some of the common MP identified in the water sources. AB - The increasing demand and use of plastics in our daily lives have caused an increase in microplastics (MPs) concentration in water bodies.
Raman spectroscopy (named after Indian physicist C. V. Raman) is a spectroscopic technique typically used to determine vibrational modes of molecules, although rotational and other low-frequency modes of systems may also be observed. Raman spectroscopy is commonly used in chemistry to provide a structural fingerprint by which molecules can be identified. WebIn summary, this is the main combination scattering band that occurs from the action of monochromatic light with a crystal lattice of PS.
