We propose an ammonia spectral line study to determine the kinetic temperatures in the dense cores of the G333 giant molecular cloud complex. The temperatures will be used to constrain spectral energy distribution modelling of the dense cores to determine the luminosity and mass. Ammonia is an excellent molecular cloud thermometer and is perfectly suited to this task. This project is part of a larger investigation to understand the timescales and evolutionary sequence associated with high-mass star formation, particularly the earliest stages. The properties of the dense cores within G333, as determined from this project, will be used in conjunction with the Mopra observations and other indicators of evolutionary state (e.g. maser emission) to determine the relative evolutionary state of the cores throughout the complex. Assuming that all the cores in the same complex are formed from the same gas with largely the same initial chemical abundances, the molecular variations between the cores are more likely to reflect differences in evolutionary state between the cores rather than in a more heterogeneous sample of cores.
