The infrared emission in supernova remnants (SNRs) is a complex combination of gas-phase line emission, PAH-band emission, and thermal continuum from dust, as well as less prominent source. This presents the observer with both challenges and opportunities. In this poster we take a look at some of the first results from our infrared spectral mapping on the SNR N49 in the Large Magellanic Cloud. We will briefly discuss the data reduction and background subtraction for our maps and spectra for this remnant, and will highlight areas on and off the SNR showing relative line versus continuum emission. We will also display narrow band maps in specific molecular and ionic lines, and use line ratio analysis and blackbody and dust fits on selected regions to infer physical properties of hot gas and dust within N49.
