| Abstract: | We present the results obtained with a radiative transfer model to investigate the excitation of OH molecules. Maser pumping efficiencies are estimated from the model and compared to the value calculated using recent OH far-infrared (FIR) observations with ISO and OH maser data. This revised version was published online in August 2006 with corrections to the Cover Date. |
