WebBased on theoretical stretching frequencies, new interpretations are proposed for some of the bands experimentally observed in synthetic samples of dravite and magnesio-foitite. 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. fix shapewear
