✦ Synopsis


ne rotational spectrum of formic anhydride (C2fIZ03) has been studied and assigned in the frequency rl~lge from 8 to 40 GHz. The rotational constants, ccnirilxgzl distortion constants and the electric dipole moment have been determined for the pound vibrational state. The most stable conformation of the molecule has been determined.

* The reagenis were obtained from Fluka AG, Bucks, Switzerland.

The microwave spectrum of methyl vinyl sulfone, \(\mathrm{CH}_{2} \mathrm{CHSO}_{2} \mathrm{CH}_{3}\), has been investigated in the frequency region 26.5 to \(40 \mathrm{GHz}\). The assigned transitions are consistent with a conformation in which one of the \(\mathrm{S}=\mathrm{O}\) bonds nearly ecl
