Webthis paper, we discuss only the “absorption versus wavenumber” curves. In short, the IR spectrum is divided into three wavenumber regions: far-IR spectrum (<400 cm-1), mid-IR spectrum (400-4000 cm-1), and near-IR spectrum (4000-13000 cm-1). The mid-IR spectrum is the most widely used in the sample analysis, but far- and near-IR WebAug 4, 2009 · Wavenumbers for Calibration of IR Spectrometers, Description of Tables The tables accompanying the spectra contain all the lines that went into the calculation of the spectrum and should contain all lines that might interfere with the calibration lines.
