We propose an NH3 spectral line study of southern massive star formation sources that have been mapped in millimetre continuum emission using the SIMBA bolometer on the SEST. Following a multiwavelength investigation into these cores, using followup and existing submillimetre continuum observations as well as archival infrared data, we have drawn spectral energy distribution (SED) diagrams for the cores. SED profiling reveals source specific parameters such as their temperature and luminosity. Analysis of our SED fits indicates a differentiation in temperature for cores devoid of methanol maser sources and/or UC HII regions compared to those associated with these objects. This has led us to propose that this temperature differentiation is indicative of an evolutionary sequence for the cores in our sample. We now need an independent determination of the temperature of the cores in order to test the robustness of our SED fits and hypotheses drawn from these fits. A systematic determination of the temperature of all the cores in the sample will allow determination of the temperature and subsequent analysis of cores without enough data to SED profile. Ammonia is an excellent molecular cloud thermometer and is perfectly suited to this work.
