Scientific paper
We will obtain small maps and pointed spectral observations of key locations in massive star-forming regions. The spectra will sample the broad emission features, atomic fine structure lines, and dust continuum emission in the 5-20 micron spectra. Spectra and images of the PDRs in the regions will be matched with models of macromolecular chemistry and PAH emission. The IRS spectra will allow us to determine important physical and evolutionary parameters for the PDRs, such as their UV flux, and gas and electron temperatures and densities. Comparison with synthesized spectra based on the chemical models will yield the distribution of the size and charge of the emitters.
