WebNov 30, 2015 · Vibrating bonds absorb infrared energy at a frequency that corresponds to the vibrational frequency of the bond. In organic chemistry, this corresponds to frequencies of 15 to 120 THz. These frequencies are expressed as wavenumbers: wavenumber = frequency speed of light = ν c. So the wavenumbers range from 500 to 4000 cm⁻¹. black and blue مترجم
