Lett. 237, 51 (1980).Author Institution: Emory University, Atlanta, GA 30322The wavelength-resolved fluorescence excitation technique has been used to record the (0,0) bands of the $e^{3}\Pi_{1}- a^{3}\Delta_{1}$ and $e^{3}\Pi_{2} - a^{3}\Delta_{2}$ electronic transition of ZrO at a resolution of $0.03 cm^{-1}$. Those data were combined with previous high resolution $analyses^{1.2}$ to obtain an accurate term energies for the triplet state manifold of ${^{90}}Zr^{16}O$. The principal constants (in $cm^{-1}$) obtained from recent and previous analyses are: $\begin{figure}\end{figure}$ Work supported by AFOSR under grants F19628-90-C-025 and F49620-92-J-0215
