Recent radio observations at 18 cm have found a number of new OH stars, all of which exhibit the double-peaked spectrum characteristic of these objects. They confirm the correlation between stellar period and the velocity separation of the two emission peaks. A less stringent correlation seems to exist between the I-K color index and the velocity separation.
