WebJul 1, 2024 · Their structural framework consists of a C=O group and two C-O bonds. This gives rise to three intense peaks called the Rule of Three with peak positions at approximately 1700, 1200, and 1100 wavenumbers. The three vibrations involved are the C=O stretch, a C-C-O stretch, and an O-C-C stretch. WebThe prominent feature of the IR spectra of these compounds is the absence of the usual carbonyl band in the 1620–1720 cm −1 range and the presence of two or more strong bands in the 1500–1610 cm −1 range, a fact considered as the result of a short distance O–S interaction. teaming rentalWebThe IR bands simply indicate the type of bond. The O-H indicates an alcohol, and the C=O indicates a ketone. Combined in one spectra they may indicate an organic acid or possible ester. sowa power station boston directions
