✦ Synopsis

The wavelength-resolved fluorescence excitation technique has been used to record the ((0,0)) bands of the satellite (e^{3} \Pi_{1}-a^{3} \Delta_{1}) and (e^{3} \Pi_{2}-a^{3} \Delta_{2}) transitions of ZrO at a resolution of (0.03 \mathrm{~cm}^{-1}). These data were combined with previous high-resolution analyses of the ZrO (\beta) system (B. Simard et al., Faraday Discuss. Chem. Soc. 86, 163-180, 1988) and with the analysis of the intercombination (e^{3} \Pi_{1}-X^{1} \Sigma^{+})transition (P. D. Hammer and S. P. Davis, Astrophys. J. Lett. 237, 51-53, 1980) to obtain accurate term energies for the triplet states of ({ }^{\text {") }} \mathrm{Zr}^{\mathrm{t}} \mathrm{O}). Ligand field theory calculations were used to suggest electronic configurations for the excited states of ZrO. 1995 Academic Press. Inc.
