Zirconia (ZrO2) is an important material with applications in microelectronics, catalysis, and ceramics. Previously the photoelectron spectrum of the ZrO2 anion and the pure rotation spectrum of the neutral have been recorded and analyzed. Here we present the first observation of the visible spectrum of ZrO2 via laser induced fluorescence (LIF) and resonance enhanced multi-photon ionization (REMPI). The LIF spectrum was recorded between 17000-18900 Cm-1 at a resolution of 0.2 Cm-1 using pulsed dye laser excitation and tentatively analyzed to give harmonic vibrational parameters ω1, ω2, and ω3 for the tilde{A}1B2 state of 495(1) Cm-1, 150(3) Cm-1 and 1045(4) Cm-1, respectively. Dispersed fluorescence spectra of thirteen bands were recorded and analyzed to give harmonic vibrational parameters ω1, ω2, and ω3 for the X1A1 state of 898 (1) Cm-1, 287(3) Cm-1 and 808(4) Cm-1, respectively. The radiative lifetimes of numerous bands have been measured and analyzed. Franck-Condon factors were calculated and used to model the REMPI and excitation spectra. A comparison with TiO2 is made.
