Webiv) weak overtone and combination bands are useful indicators of an aromatic compound and will usually be easily noticed in the region around 2000-1667 cm-1. Don't forget that other groups can give IR bands that … WebIn contrast, these overtone and combination bands are much weaker for isomer B, implying that the 1ππ* state of B is planar and decoupled from the 1nπ* state. These observations agree with the calculations, which predict the 1nπ* above the 1ππ* state for isomer B but below the 1ππ* for both 9H-2AP and isomer A.",
