During a survey for silicon monoxide (v = 0, J = 1-0) emission from compact and ultra-compact H II regions, detections were made toward 12 Galactic H II regions. A comparison is drawn with the v = 0, J = 2 - 1 SiO observations of the same regions. It is found that most of the detected SiO emission probably originates from compact, hot, optically thick sources. The observed large line widths, suggest that the SiO sources are probably associated with outflowing material from embedded young stars. Silicon monoxide (v = 0, J = 1-0) absorption was also detected from the H II region Sgr B2. This absorption feature has a similar line width to that observed in other low-optical depth molecules toward this source such as NH3 and H2CO.
