The sensitivity of Spitzer is much better than that of ground-based telescopes in the mid-infrared, but Spitzer is limited in spatial and spectral resolution.
Using TEXES on the NASA IRTF and Gemini North, we have have studied three high-mass star formation regions with 0.5-1.5" spatial and 3-4 km/s spectral resolution.
In Orion we observed outflow of C2H2 and HCN through holes in the KL cavity walls and resonant scattering of radiation from the hidden luminosity sources by molecules in the surrounding ambient gas.
In W51 IRS 2 we observed a massive jet emerging from a molecular cloud into an HII region, where it is being photoionized by radiation from a young OB star cluster.
In NGC 7538 IRS 1 we observed ionic line emission and molecular line absorption from the surface of an edge-on disk around a massive star.
The combination of high spatial and high spectral resolution provided a more complete picture than had been available of these prototypical high-mass star formation regions.
