dc.description.abstractThe electronic transition spectrum of yttrium monoxide (YO) in the spectral region between 284nm and 307nm has been recorded using laser ablation/reaction free-jet expansion and laser induced fluorescence (LIF) spectroscopy. The YO molecule was produced by reacting laser-ablated yttrium atoms with O$_{2}$ seeded in argon. Twenty transition bands were observed in that region and a few bands were selected for further study using optical-optical double resonance (OODR) spectroscopy. The excited C$^{2} \Pi$ state has been reached via the intermediate B$^{2} \Sigma^{+}$ state from the ground X$^{2} \Sigma^{+}$ state. The excited sub-states observed so far have $\Omega$ = 0.5 and 1.5. A least squares fit of the measured rotational lines yielded molecular constants for the newly observed excited states.en_US
