Abstract:
The Arecibo 1612MHz survey of a complete sample of color-selected IRAS
sources with 25µm fluxes S(25)>2 Jy detected 393 OH/IR stars. A
complementary 1667 and 1665MHz OH survey of these objects is presented
here. Main-line masers have been detected in 238 surveyed objects: 18
exhibit only 1665MHz emission, 220 exhibit 1667MHz masers, and 119
exhibit both. The main lines were not detected in 159 objects.
