 Title    High Resolution Microwave Spectroscopy of Ethyl Vinyl Ether: Accurate Determination of the Methyl Top Internal Rotation Barrier  
 Abstract    We have performed an investigation of the internal rotation of the methyl group in trans-cis ethyl vinyl ether by using molecular beam-Fourier transform Microwave (MB-FTMW) spectroscopy. Rotational spectra (up to J = 20) were recorded in the frequency region 4-19 GHz. Due to the internal rotation of the methyl group, some rotational transitions were split and the torsional barrier could be determined to V 3 (CH 3) = 1074.4(4) cm -1 .

 Title    Observation of Carbonyl Fluoride, Ketene, Acetic Acid and Fluorocarbene Produced by an Electric Discharge within a Nozzle by Molecular Beam Fourier Transform Microwave Spectroscopy. A Reaction via a Cycloaddition for Carbonyl Fluoride and Keten?  
 Abstract    A molecular beam Fourier transform microwave spectrometer, designed for the study of chemical reactions within electrical discharges, is described in detail. Applications include the production of carbonyl fluoride, ketene, acetic acid, and difluorocarbene. For the production of carbonyl fluoride and ketene with 1,1-difluoroethylene and carbon dioxide as precursor molecules a reaction path via a 2+2 cycloaddition is proposed.
