WebTo use an IR spectrum table, first find the frequency or compound in the first column, depending on which type of chart you are using. Then find the corresponding values for absorption, appearance and other attributes. The value for absorption is usually in cm -1. Note that not all frequencies have a related compound.

The unit for near-, mid-, and far-infrared, the wavenumber (cm -1 ), is derived from the inverse relationship between wavelength and frequency. Figure 1.
