WebFTIR Spectroscopy Principles The electromagnetic spectrum consists of different regions corresponding to different energy (E), frequency (ѵ), and wavelength (λ) ranges as seen in Figure 1. The unit for near-, mid-, and far-infrared, the wavenumber (cm -1 ), is derived from the inverse relationship between wavelength and frequency. Figure 1. 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 …
