The absorption spectrum obtained from an IR spectroscopy measurement provides valuable information about the molecular structure of the sample. The position, shape, and intensity of the absorption ...

and bending vibrations (rocking and twisting types), and based on these vibrations the functional groups in the molecules are determined. Infrared spectroscopy products such as Fourier transform ...

Using Fourier-transform infrared (FTIR) spectroscopy, transmission electron microscopy (TEM), and scanning electron microscopy (SEM), they identified key functional groups and detailed the ...
