Profiles of the 3.3 and 3.4 μ m features (left) and the 8.2 μm and 11.4 μ m features (right) of Nova V705 Cas at two different epochs (253 and 320 days after outburst, shown as solid and broken lines respectively). These detections show that organic solids can condense easily from the gas phase in the circumstellar envirnoment. Figure adapted from Evans et al. (2005).
