Abstract
The microwave spectrum of the second conformer of acrolein has been assigned. Rotational constants A=22831.650 (16) MHz, B=6241.047 (3) MHz and C=4902.206 (3) MHz of s-cis acrolein in the vibrational ground states were determined from 42 transitions between 8 and 60 Ghz. The small value of the inertia defect establishes the planarity of the molecule. Rotational transitions in excited states of s-cis and s-trans acrolein have been analyzeed. The shifts of the rotational constants upon vibrational excitation have been interpreted on the basis of a flexible model for torsional motions and vibrational interactions.
