Abstract

Coronene encapsulated in a KBr pellet has been heated over a range of temperatures up to 788 K and its mid—infrared absorption spectrum obtained at selected temperatures. Changes in the aborbance spectum at elevated temperatures include a 3—fold strengthening of coronene’s 3.29 µm band which assumes a profile very similar to the 3.29 µm UIR band. Coronene’s 8.8 µm feature which is also correlated with a UIR also shows substantial increases in intensity at elevated temperatures. The 10.5 µm feature of coronene which does not correlate with the UIR decreases sharply as the temperature is increased. These results as well as some possible implications are discussed.
