The broadband pure rotational spectra of CD3CDO, 13CD3CDO, CD313CDO, and CD3CD18O have been recorded using a BrightSpec W-Band (75–110 GHz) chirped-pulse Fourier transform millimeter wave (CP-FTmmW) spectrometer. The sample was enriched with deuterium, whereas the 13C and 18O isotopologues were observed in natural abundance (with respect to the enriched fully deuterated parent containing 12C and 16O). The analysis of the spectra is described and the derived molecular constants are compared to those of known acetaldehyde isotopologues. Furtherm...
