Ammonia observations at radio wavelengths have proved to be a useful probe of the physical parameters of dense molecular cores. We wish to test the models of the "hot cores" found in regions of massive star formation which are thought to be the birthplaces of O stars. We want to do this using the rotational transitions of ammonia which can be observed by the LWS. We expect to observe absorption lines in many of our sources which will allow us to probe a different regime than that available to radio observers.
