WebDec 5, 2014 · You can think of it in terms of, if there is little or no conjugation, the electrons are firmly based in the $\ce{C=O}$ bond. As soon as we introduce some resonance structure, or conjugation, now those electrons can delocalise over 3-4 atoms or even more. This weakens the $\ce{C=O}$ bond, moving the IR peak down to lower wavenumbers. WebSep 1, 2024 · Across all the installments I have written so far there has been an overarching structure: Each large section has been devoted to the infrared (IR) spectroscopy of a specific chemical bond. We started with the C-H bond, moved on to the C-O bond, and now it is time to discuss the spectroscopy of the C=O or carbonyl group.
