Spitzer Space Telescope Spectroscopy of Comets

We present spectra of comets observed with the Infrared Spectrograph (IRS) on the Spitzer Space Telescope. The observations are based on a select set of comets with high-quality data, reduced using a uniform approach. We summarize the observations, and detail our reduction methodology. Additional details on the calibration of cometary sources with the IRS instrument are also given, and plots of all spectra are included for reference.
