The millimeter-wave absorption spectrum of acrolein has been investigated in the 59.6–120 GHz region with a Free-Jet Absorption MilliMeter Wave spectrometer. New measured rotational transitions belonging to the s-cis conformer and its three 13C isotopologues and those of 13C and 18O isotopologues of the s-trans conformer, observed in natural abundance, are reported.

Rotational transitions of 16012C32S and 16013C32S in the ground vibrational state and of 16012C32S in several excited states have been accurately measured in the millimeter wave region for a minimum of four different J values. The analysis of the measured frequencies leads to rotational constants for the following vibrational states: 0 00 0 of 16O13C32S and 0 00 0, 0 1 1c 0, 0 1 1d 0, 0 20 0, 0 22c 0, 0 22d 0, 0 00 1 of 16O12C32S. Since the two components of the 0 22 0 transitions were resolved, an analysis of the l-type resonance was carried out and the interval 0 22 0 - 0 20 0 has been determined to be -4.63(10) cm-1. The result is in good agreement with the presently available determination of this level from vibrational spectra.
