Overtone band - Wikipedia

WebA band shift of the first overtone occurs for XH bands due to a hydrogen bond and an interaction between molecules as in the case of an IR spectrum. The shift is much bigger than that of the corresponding IR band. 5. In the NIR region, OH and NH stretching bands of monomeric and polymeric species are better separated compared with the IR region. 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.
