Fourier-transform infrared spectroscopy - Wikipedia

Fourier-transform infrared spectroscopy (FTIR) is a technique used to obtain an infrared spectrum of absorption or emission of a solid, liquid or gas. An FTIR spectrometer simultaneously collects high-spectral-resolution data over a wide spectral range. This confers a significant advantage over a dispersive spectrometer, which measures intensity over a narrow range of wavelengths at a time.

FTIR analysis of adsorption of poly diallyl-dimethyl ...

When macromolecule polymer is adsorbed on surface, kaolinite particles may be flocculant due to the bridging effect. There are cation flocculant characteristic bands on the spectrum of kaolinite but no obvious shifting. Thus, the adsorption of poly diallyl-dimethyl-ammonium chloride on kaolinite surface is physical adsorption.

Diallyl phthalate | C14H14O4 - PubChem

The UV spectrum of diallyl phthalate in water was found to have absorbance near 275.5 and 281 nm and is expected to have absorption shoulders which extend beyond 290 nm and therefore may be susceptible to direct photolysis by sunlight. If released to soil, diallyl phthalate is expected to have low mobility based upon an estimated Koc of 1,360.
