Laser excitation spectroscopy of SrOD and BaOH and optical optical double resonance spectroscopy of SrOD have been carried out at high-resolution. SrOD and BaOH were produced by the reaction of metal vapor and D2O/H2O vapor in a Broida-type oven and in a laser ablation/molecular beam spectrometer, respectively. For SrOD, the A 2 - X 2 + and C 2 - A 2 transitions were observed and rotationally analyzed for the first time. Combined with the previous microwave data from the literature, the present data were fitted using the usual 2 and 2 Hamiltonians, and spectroscopic constants were obtained for the X 2 + (000), A 2 (000) and C 2 (000) states of SrOD. For BaOH, the A 2 - X 2 + transition was observed and rotationally assigned. Unfortunately, one spin component of this transition could not be calibrated since our Ti:Sapphire laser had very low output power.
