Ir important peaks
WebAn FTIR spectrophotometer is mainly used to estimate the structure of organic compounds. This instrument shines infrared light onto the molecules, which absorb infrared radiation equivalent to the interatomic vibrational energy of the atoms comprising the molecules. WebJul 1, 2024 · The IR Spectroscopy of Esters Note that ester groups contain one C=O bond and two C-O bonds. We have already studied the IR spectroscopy of both these functional groups, so we can take a stab at predicting what their spectra might look like.
