Spectra from the Short Wavelength Spectrometer (SWS) on {\em Infrared Space Observatory} exhibit artifacts at 4.5 and 8~\mum. These artifacts appear as spurious broad emission features in the spectra of stars earlier than F0, such as \alpha CMa. Comparison of absolutely calibrated spectra of standard stars to corresponding spectra from the SWS reveals that these artifacts result from an underestimation of the strength of the CO and SiO molecular bands in the spectra of sources used as calibrators by the SWS.
