Raman spectra of a -chitin standard from A. aerophoba , …
WebThe Raman spectra of the obtained chitin–Fe 2 O 3 composites show the presence of four very intense peaks characteristic of hematite (vertical lines). It is known 76 that the position and width of the hematite nanoparticles peaks at 226 cm −1 and 412 cm −1 (Fig. S2 ESI † ) are influenced by the nanoparticles' dimensions. WebFeb 23, 2024 · In order to determine the DD of the chitin and chitosan samples, the coherent anti-Stokes Raman spectroscopy (CARS) has been applied in this study. The changes in the intensity of the resonant bands, related to the vibrations of acetamide group, were utilised as an indicator of the DD. hawthorn gardens il
