WebThe infrared stretching frequencies of these groups vary in the same order, ranging from 1100 cm -1 for C-N, to 1660 cm -1 for C=N, to 2220 cm -1 for C≡N. If one of the bonded atoms (m 1 or m 2) is a hydrogen (atomic mass =1), the mass ratio in the equation is roughly unity, but for two heavier atoms it is much smaller.

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.
