A supersonic molecular beam sample of rhodium monoxide, RhO, has been generated using a laser ablation/chemical reaction generation scheme and probed using near natural line width limited optical Stark spectroscopy utilizing laser induced fluorescence detection. Stark splittings in the SR11(0) and SR11(1) lines of the [15.8] and [16.0] 2 Pi1/2 - X4 Sigma- (0,0) transitions were observed upon application of static electric fields up to 2400 V/cm. Comparisons of the determined field-free molecular parameters is made with previous work'\footnoteR.H. Jensen, S.G. Fougère, and W.J. Balfour, Chem. Phys. Lett. \textbf370, 106-111 (2003).'\footnoteR.F. Heuff, S.G. Fougère, and W.J. Balfour, J. Mol. Spectrosc. \textbf231, 99-107 (2005).. Progress on the analysis of the Stark effect will be reported.
