WebInfrared (IR) spectroscopy is one of the most common spectroscopic techniques used by organic and inorganic chemists. Simply, it is the absorption measurement of different IR frequencies by a sample positioned in the path of an IR beam. The main goal of IR spectroscopic analysis is to determine the chemical functional groups in the sample. WebWavenumber, as used in spectroscopy and most chemistry fields, is defined as the number of wavelengths per unit distance, typically centimeters (cm −1): ~ =, where λ is the …
http://www.chem.ucla.edu/harding/IGOC/W/wavenumber.html WebWe have a higher frequency of vibration, we get a higher wave number. So the signal for this carbonyl appears at a higher wave number, so approximately 1800, or even a little bit higher than that, so 1815 or so. So once again, that's the approximate value for the signal of the carbonyl for an acyl or acid chloride.
