Abstract

Laboratory experiments have been conducted on binary ice mixtures and sequentially-deposited layers of CO with CO₂, CH₄, and CH₃OH. Spectra were recorded at 0.5 cm^-1 resolution as the ices were heated, from 15 to 100 K. The results show that layered and mixed ices exhibit different spectroscopic traits and physical behavior. The astrophysical implications of these data are discussed, with particular reference to the recent detections of solid CO in star forming regions.
