Abstract: We present new 3mm observations of the W51 region, centered on W51IRS1, including the H II regions W51d, and W51e. The SO2 [8(1,7)-8(0,8)], SO2 [8(3,5)-9(2,8)] , SiO (J=2-1, nu = 0), and H13CO+ (J=1-0) have been mapped. and SiO lines show molecular gas centered roughly on W51e4, an UCHII region detected at centimeter wavelengths.
