WebFTIR stands for Fourier transform infrared, the preferred method of infrared spectroscopy. When IR radiation is passed through a sample, some radiation is absorbed by the sample and some passes through (is transmitted). The resulting signal at the detector is a spectrum representing a molecular ‘fingerprint’ of the sample.

WebSeveral years ago, Nyquist and Potts published a paper on the characteristic frequencies of thiol esters and related compounds, in which they concluded that the C—S stretching frequency of the [Equation] group lies in the 880 to 1030 cm−1 region. Their assignment of the C—S stretch in thiolacetic acid to the band at 993 cm−1 is in conflict with the … WebAn infrared spectroscopy correlation table (or table of infrared absorption frequencies) is a list of absorption peaks and frequencies, typically reported in wavenumber, for common …
