Abstract: The vibrational absorption spectra of 2-oxetanone, and its 4- and 3-methyl derivatives and the vibrational circular dichroism (VCD) spectra of 4- and 3-methyl-oxetanone are predicted using harmonic force fields calculated at the MP2 level of approximation. The results are compared with the predictions of SCF harmonic force fields and with available experimental data. The spectra calculated using 6-31$G^{*}$ and 6 -31$G^{**}$ MP2 force fields lead to nearly unambiguous assignment of the experimental spectra of 2-oxetanone, 4-methyl-2-oxetanone and 3-methyl-2-oxetanone.""
