The FTIR generates spectra with patterns that provide structural insights, for those groups in different molecules, The actual frequency is affected by the environment, so the reference chart shows wide bands rather than specific frequencies, The identification of functional groups is a cornerstone of IR spectroscopy and organic chemistry, Spectral Range Chart, Flexible FTIR spectrometers
records spectra from an upper limit of around 4000cm 1 by convention down to 400cm 1 as defined by the optics of the instrument commonly based on potassium bromide KBr For this reason when a spectral region is quoted in the text the higher value will be quoted first consistentwiththe normal left-to-right hightolow cm 1 representation of spectra, Also, the terms infrared band, peak

These spectra-structure correlations are the result of work by many investigators Major contributions have been made by A Lee Smith and his colleagues at Dow Corning Corporation In addition to previously-published data, we have included some correlations based on our experience in the analysis of organosilicon compounds, There is increasing interest in carbon-containing silicon compounds as
