Scientific paper

We present SWS spectra taken across the M17-Southwest photodissociation
front and discuss spectral properties of PAHs and VSGs. We report new
features at 4.65, 6.35, 8.7 and 11μm which we interpret as PAHs
and/or VSGs emission. From feature intensity ratios along the cut, we
find PAHs are mainly ionized and almost fully hydrogenated.
