Recent observations of TNOs include possible detections of C2H6 (ethane) and CH3OH (methanol) from absorptions in their infrared spectra. Our measurements of pure materials and mixtures have demonstrated that absorptions can shift in location and change in shape and strength when materials are mixed and compared to end member spectra. We will concentrate of the changes in the absorptions in the region from 2 to 2.5 μm, since these are the most commonly used regions for ground based observing. Since there are multiple stable phases of CH3OH and C2H6 at the temperature range seen on TNOs, we will the possibility of detecting different phases of these ices.
