✦ Synopsis

The microwave spectrum of NiO in the 3E-electronic ground state has been observed using a source-modulated millimeter and submillimeter wave spectrometer. NiO was generated by dc-sputtering vaporization of powdered NiO. Rotational transitions of 5sNiO and 6°NiO in the vibronic ground state were measured in the 110-460 GHz region and those of 5sNiO in the v = 1 state in the 240-370 GHz region. Precise molecular constants were obtained by a least-squares analysis of the measured frequencies. The r e bond length is obtained to be 1.6271291(31) A with three standard errors in parentheses.
