WebFeb 2, 2016 · This is the stretching mode of the carbonyl bond. In the space of one second, the spring 'bounces' back and forth 5.15 x 10 13 times - in other words, the ground-state frequency of carbonyl stretching for a the ketone group is about 5.15 x 10 13 Hz. WebA simple way of estimating this is to set the mass of all but two of the atoms to a very small value (0.00001), leaving only the masses of the C and O as normal; this is shown as a reduced frequency in the table above. The harmonic CCSD (T)/6-311G (d,p) C=O “pure” mode reduces to 1764 for methyl ethanoate and 1743 cm -1 for propanone.
