The first detection of strong maser emission from high J rotational transitions of the first vibrational excited state of (Si-29)O is presented. Low upper limits have been reached for the emission of the J=2-1, J=3-2, and J=5-4 lines of the same vibrational level toward all the stars in the sample. It is proposed that the thermal overlap of the infrared lines of (Si-28)O with those of (Si-29)O plays an important role in the pumping of the (Si-29)O masers in the v = 1 state. Infrared overlaps between these two isotopic species of silicon monoxide could also explain the (Si-29)O v = 0 masers.
