WebJan 26, 2013 · Originally, IR spectra were presented in units of micrometers. Unfortunately, a linear axis in micrometers compresses the region of the spectrum 10-15 mm) that usually has the largest number of peaks. One could rectify this by presenting the speectrum on a linear scale vs. frequency (Hz), but the magnitude is unwieldy (10 mm = 3 x 10 13 Hz).
