Fourier transform infrared ftir spectrometer

The surface of the MS specimen immersed in 1.0 M H₂SO₄ for 24 h in the absence and presence (400 and 1000 ppm) of plant extract was observed using a Bio-Logic modular scanning electrochemical microscope (M470 Ac-SECM). After retrieval from the test solution, the surface of the MS specimens was cleaned in running water with the help of a brush to remove corrosion products, degreased with acetone, dried, and preserved in desiccators. The specimen surface was gold-coated to obtain high-quality images. Surface analyses of specimens were performed at different locations to assure reproducibility of the results.
The plant extract was analyzed by an IRAffinity-1S Shimadzu Fourier transform infrared (FTIR) spectrometer to assign the various functional groups present in it. This model operates in attenuated total reflectance (ATR) mode.

A Fourier transform infrared
(FTIR) spectrometer was used to perform
functional chemistry studies (Shimadzu, Kyoto, Japan). The functional
group variations at different wavelengths were investigated. The FTIR
spectra were obtained using an attenuated total reflection FTIR (ATR-FTIR)
spectrograph with an average of 34 scans and a spectral resolution
of 4 cm^–1 over a range of 500–4000 cm^–1.

The chemical bond structure of halochromic films was studied by a Shimadzu Fourier transform infrared (FTIR) spectrometer (Shimadzu, Japan) in the range of 400–4000 cm⁻¹ at a resolution of 4 cm⁻¹. X-ray diffraction (XRD) patterns of halochromic film samples were taken with the TA-instrument (USA) X-ray diffractometer in a 2θ range of 10° to 80° with Cu-Kα radiation.
