  In this work we present, for the first time, infrared spectra of Titan from
the Spitzer Space Telescope ($2004-2009$). The data are from both the short
wavelength-low resolution (SL, $5.13-14.29\mathrm{\mu m}, R\sim60-127$) and
short wavelength-high resolution channels (SH, $9.89 - 19.51\mathrm{\mu m},
R\sim600$) showing the emissions of CH$_{4}$, C$_{2}$H$_{2}$, C$_{2}$H$_{4}$,
C$_{2}$H$_{6}$, C$_{3}$H$_{4}$, C$_{3}$H$_{6}$, C$_{3}$H$_{8}$, C$_{4}$H$_{2}$,
HCN, HC$_{3}$N, and CO$_{2}$. We compare the results obtained for Titan from
Spitzer to those of the Cassini Composite Infrared Spectrometer (CIRS) for the
same time period, focusing on the $16.35-19.35\mathrm{\mu m}$ wavelength range
observed by the SH channel but impacted by higher noise levels in CIRS
observations. We use the SH data to provide estimated haze extinction
cross-sections for the $16.67-17.54\mathrm{\mu m}$ range that are missing in
previous studies. We conclude by identifying spectral features in the
$16.35-19.35\mathrm{\mu m}$ wavelength range, including two prominent emission
features at 16.39 and $17.35\mathrm{\mu m}$, that could be analyzed further
through upcoming James Webb Space Telescope Cycle 1 observations with the
Mid-Infrared Instrument ($5.0-28.3\mathrm{\mu m}, R\sim1500-3500$). We also
highlight gaps in current spectroscopic knowledge of molecular bands, including
candidate trace species such as C$_{60}$ and detected trace species such as
C$_{3}$H$_{6}$, that could be addressed by theoretical and laboratory study.
