WebSep 29, 2024 · Why do overtones appear in vibrational spectroscopy? 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.
