Overtones occur when a vibrational mode is excited from v=0 to v=2 (the first overtone) or v=0 to v=3 (the second overtone). The fundamental transitions, v=±1, are the most commonly occurring, and the probability of overtones rapid decreases as Δv>±1 gets bigger.

In vibrational spectroscopy, an overtone band is the spectral band that occurs in a vibrational spectrum of a molecule when the molecule makes a transition from the ground state (v=0) to the second excited state (v=2), where v is the vibrational quantum number (a non-negative integer) obtained from solving the Schrödinger equation for the molecule. Generally, in order to study the vibrational spectra of molecules, chemical bond vibrations are as… WebThe wavelength of the fundamental O - H stretching vibration is about 3. 0 µm.
