Using the superheterodyne sub-millimetre spectrometer at the Micro-wave Laboratory of the University of Lille I, France some hitherto unavailable pure rotational trasittons have been measured for the ketene molecule (CH2CO). The measurements were extended up to almost 800 GHz and contained a-type ΔKa=0 transitions. These new data were then used in conjuction ground-state combination differences recalculated from an earlier high-resolution infrared study of ketene. This data set was used to re-derive ground state rotational constants for ketene both in the A and S reduction scheme of Watson.
