WebApr 3, 2024 · The FTIR spectra of 3mol% glycine doped ZTS shows (fig.2b) a broad envelope lying in between 2750 and 3500cm-1 arising out of symmetric and asymmetric modes of NH2 group of zinc coordinated thiourea. 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-resolution spectral data over a wide spectral range. This confers a significant advantage over a dispersive spectrometer, which measures intensity over a narrow range of wavelengths a…
