Place the second plate on top and make a quarter turn to obtain a nice even film. Place the plates into the sample holder and run a spectrum. If the sample is too concentrated, separate the plates and wipe one side clean before putting them back Notice: Except where noted, spectra from this collection were measured on dispersive instruments, often in carefully selected solvents, and hence may differ in detail from measurements on FTIR instruments or in other chemical environments.

Early days COLLECTING AN FTIR SPECTRUM There are three quick, simple steps involved in obtaining a spectrum of a sample: STEP 1 Record a spectrum with no sample present. (Known as a ‘background’.) STEP 2 Insert the sample into the spectrometer.

output spectrum are calculated from the known frequency of the laser light. An FTIR spectrometer easily achieves frequency precision and accuracy of better than 0.01 wavenumbers. This means that spectra collected with an FTIR spectrometer can be quantitatively compared whether they were collected five minutes or five years apart.
An FTIR spectrum arises from interferograms being ‘decoded’ into recognizable spectra Patterns in spectra help identify the sample, since molecules exhibit specific IR fingerprints
Although optical components in Fourier transform infrared (FTIR) spectrometers are preferably wedged, in practice, infrared spectra typically suffer from the as melting point, density, refractive index, burning behaviour and FTIR spectrum.
FTIR Spectroscopy (Fourier Transform Infrared) A word about units.Most spectra using electromagnetic radiation are presented with wavelength as the X-axis. Originally, IR spectra were presented in units of micrometers. View entire compound with free spectra: 5 FTIR, and 2 Raman. SpectraBase Compound ID: 2gRC617GVIn: Mol Weight: 0.0 g/mol: Molecular Formula: HO(CH2O)nH: Exact Mass: 0 Beauchamp Spectroscopy Tables 1 Z:\classes\spectroscopy\all spectra tables for web.DOC Infrared Tables (short summary of common absorption frequencies) The values given in the tables that follow are typical values. Specific bands may fall over a range of wavenumbers, cm-1. Specific substituents may cause variations in absorption frequencies. Fourier transform infrared (FTIR) spectra were obtained with a Shimadzu spectrophotometer, over a scan range of 500–4000 cm − 1 with an average 16 scans.
