Abstract : The microwave spectrum of XeOF4 was investigated in the region of 20-40 kMc with a conventional Stark modulated spectrometer. Transitions were observed for five naturally-occurring isotopes of xenon in the 016 species and for two of these isotopes in an 018 enriched sample. The simplicity of the spectrum and its first order Stark effect are characteristic of symmetric tops. From the rotational constants of the various isotopic species the structural parameters, based on a C4v model, were calculated. The xenon-oxygen bond appears to be a little shorter in XeOF4 than in crystalline XeO3 for which X-Ray methods give 1.76 A. This is consistent with the force constants measured for the two compounds: 7.10 md/A for XeOF4 and 5.66 md/A in XeO3. (Extracted)
