Abstract
The microwave spectra of the heavy atom isotopomers of 2,2-dimethyloxirane, (CH 3) 2COCH 2, were observed in natural abundance using a molecular beam Fourier transform-microwave spectrometer (MB-FTMW). The rotational constants were obtained and structures were derived using the r s, r 0, and r Δ0 methods. The r s (C–C) bond length in the ring is 1.444(6) Å, the r s (C–O) bond lengths are 1.437(2) and 1.419(7) Å, and the C(ring)–C(methyl) distance is 1.522(3) Å.
