Magnetite silica ftir spectra
WebFTIR Sample Techniques - True Specular Reflectance/Reflection-Absorption How does it work? True specular reflectance is a surface measurement technique that works on the principle of reflective efficiencies. This principle states that every sample has a refractive index that varies with the frequency of light to which it is exposed. Webto the O–Si–O bending mode.36 These same typical silica FTIR peaks are observed in the organo-functionalized SiO 2/SPION/C8 and MCM48/SPION/C8 nanocomposites, but with much lower relative intensities, as expected for the presence of an organic layer on the silica particles,36 giving rise to new bands in the FTIR spectra.
