The pure rotational spectrum of 65CuO in its ground X 2Πi state was recorded in the 198-384 GHz spectral region using a dc-sputtering absorption spectrometer. The determined 65Cu(I=3/2) hyperfine parameters are a= 214.1(35), bF= -483.6(94), c= 72.5(95), d= 134.5(34), and eQq0= -16.9(54) MHz, where a three standard deviation error estimate is given in parentheses. A plausible molecular orbital description for the X 2Πi state based upon the determined parameters is given.
