• Abstract

  A sample of 44 sources has been searched for maser emission from excited OH in the 2Pi1/2J = 1/2 state, in the three lines at 4765, 4750 and 4660 MHz. Most of the objects searched were taken from the large sample of powerful far-infrared sources previously searched for OH 18-cm emission by Cohen, Baart and Jonas. Nine sources were detected at 4765 MHz, including two new discoveries. Three of these sources were detected at 4750 MHz, including the first strong 4750-MHz maser, and two of the sources were detected at 4660 MHz. Strong variations were observed in four previously known 4765-MHz maser sources. The implication of these results for the excitation of OH and the pumping of OH masers is briefly discussed.
