WebFI-IR spectroscopy is an important method to analyze the surface structure of as-prepared composites. Fig. 2 describes the FT-IR spectrograms of β-CD, 3D-rGO and 3D-rGO/β-CD. In the β-CD curve, 3400 cm −1 and 2928 cm −1 respectively represent the stretching vibration absorption peak of O–H and CH 2 (methylene). WebMay 15, 2024 · The spectrometer Pimentel envisioned used an interference filter as its dispersive element to generate the IR spectrum, rather than a prism or a grating. This approach simplified the spectrometer and made it feasible for such an instrument to be light enough to meet NASA’s 25 lb weight maximum.
