We present infrared spectral energy distributions (SEDs) of natal super star clusters using fractal 3-dimensional radiative transfer models (Johnson et al. in preparation). A range of parameters are varied including inner and outer cluster radius, total dust mass and the fraction of 'clumpy' dust. Emission from polycyclic aromatic hydrocarbons (PAHs) is included. A comparison between the SEDs including PAH emission and those without is made. These results are an important diagnostic tool for interpreting spectroscopic observations made with the Spitzer Space Telescope, offering a more realistic physical picture than traditional 1-dimensional models.
