FTIR graph are collectively known as the fingerprint region. Each region is unique for an individual compound and are thus extremely helpful in comparisons between different FTIR graphs. The exact model used in this research was the Perkin Elmer (Model Spectrum Two) for taking spectrum data in the wavelength range of 4000-7000 cm-1. In FTIR, the clarity of the spectra (i.e., the sharpness of the peaks) obtained can be changed by selecting a different aperture. With a camera, light from the subject is projected onto film. With FTIR, an infrared radiation source is incorporated inside the instrument, the sample is irradiated with infrared radiation, and the changes in light intensity are concentrated by a detector. 1H NMR spectra of Boc amino acids; 1H NMR spectra of small molecules; 1H number of signals; Assign 1H NMR spectra to molecule; Find the structure from 1H spectrum; Number of different Hs; Peak picking.

0.2 mg of SOA was weighed and transferred into a mortar, where it was triturated with 250 mg of dry potassium bromide. Fourier Transform Infrared Spectroscopy (FTIR) identifies chemical bonds in a molecule by producing an infrared absorption spectrum. The spectra produce a profile of the sample, a distinctive molecular fingerprint that can be used to screen and scan samples for many different components. FTIR.

6 feb. 2009 — FTIR spectra were obtained after each step. Mössbauer spectra were recorded for three of the crystals when there had been a significant  GC-Direct deposition-FTIR spectra of 55 nerve agent homologues and dialkyl methylphosphonates were analysed.

Looking at the spectrum in Figure 2, the signal intensity in the vicinity of 2000 cm-1 is strong and then becomes weaker on either side of this value. On the long wavelength side, the signal reaches almost zero at 350 cm-1, which indicates that measurements cannot be made at longer wavelengths FTIR-02.
