  We present T-ReCS high spatial resolution N-band (8-13 micron) spectroscopy
of the central regions (a few kpc) of 3 local LIRGs. The nuclear spectra show
deep 9.7 micron silicate absorption feature and the high ionization [SIV]10.5
micron emission line, consistent with their optical classification as AGN. The
two LIRGs with unresolved mid-IR emission do not show PAH emission at 11.3
micron in their nuclear spectra. The spatially resolved mid-IR spectroscopy of
NGC 5135 allows us to separate out the spectra of the Seyfert nucleus, an HII
region, and the diffuse region between them on scales of less than 2.5 arcsec ~
600 pc. The diffuse region spectrum is characterized by strong PAH emission
with almost no continuum, whereas the HII region shows PAH emission with a
smaller equivalent width as well as [NeII]12.8 micron line.
