WebApr 13, 2024 · ATR-FTIR. ATR-IR measurements were performed on a Bruker Optics Tensor II spectrometer equipped with a deuterated triglycine sulfate (DTGS) detector and a Golden Gate ATR cell with a diamond crystal (Specac LTD, Orpington, UK). Spectra were acquired in the range 400-4000 cm-1 with 64 scans and a spectral resolution of 2 cm-1. … Attenuated total reflection (ATR) is a sampling technique used in conjunction with infrared spectroscopy which enables samples to be examined directly in the solid or liquid state without further preparation. ATR uses a property of total internal reflection resulting in an evanescent wave. A beam of infrared … See more Infrared (IR) spectroscopy by ATR is applicable to the same chemical or biological systems as the transmission method. One advantage of ATR-IR over transmission-IR is the limited path length into the sample. … See more • Fourier-transform infrared spectroscopy • Surface plasmon resonance See more • Harrick, N.J.
