The investigation on microwave spectrum of benzophenone was conducted with a recently constructed broadband chirped-pulse Fourier transform microwave spectrometer with a heating nozzle in the 2–8 GHz range. In this work, 138 b-type pure rotational transitions were assigned to bridge the measuring gap in the microwave region. The rotational constants for benzophenone were accurately determined by a combined microwave data fitting with frequency coverage between 2–14 GHz and have the following values: A = 1692.8892190(119) MHz, B = 412.6446602(43) MHz and C = 353.8745644(43) MHz.

Rotational transitions of eight isotopomers of tungsten monoxide, WO, in its X0+ ground electronic state, have been measured in the frequency range 22–26 GHz, using a cavity Fourier transform microwave spectrometer. The samples were prepared by laser ablation of W metal in the presence of O2 and stabilized in pulsed supersonic jets of Ne or Ar. Only the J = 1–0 transition was accessible within the frequency range of the spectrometer. It was measured for the ground (v = 0) and two excited (v = 1, 2) vibrational states. Hyperfine structure due to 183W nuclear spin-rotation coupling was found for 183WO. The overall spectral fit used a Dunham-type expression including Born–Oppenheimer breakdown parameters. Only the v = 0 and 1 states could be fit to the measurement accuracy because of a small perturbation of the v = 2 state. It was necessary to account for the finite nuclear size of the W nucleus in the fit. The resulting parameter V 01W agreed well with a value calculated using density functional theory. Equilibrium internuclear distances re have been evaluated.
