Abstract: (arXiv)
The Infrared Spectrograph (IRS)is one of the three instruments on board the Space Infrared Telescope Facility (SIRTF) to be launched in December 2001. The IRS will provide high resolution spectra R~600 from 10--37microns and low resolution spectra R~60 from 5.3--40microns Its high sensitivity and ``spectral mapping-mode'' make it a powerful instrument for observing both faint point-like and extended sources.
