Theoretical electronic structure calculations were used to investigate reactions between formaldehyde (H 2 CO) and both hydrogen cyanide (HCN) and isocyanide (HNC) in search of other favorable reactions such as ammonia-formaldehyde addition, which was found in a recent theoretical study to be strong

indicate that ices containing formaldehyde (H 2 CO) and at least a trace of ammonia (NH 3 ) will undergo reactions as the samples are heated from 10 K with no additional irradiation. A residue composed of higher-boiling-point organic species persists to 190 K and beyond. Spectral changes indicate th
As suggested by W. T. Huntress et al. (1991, Nature 352, 316-318), carbon suboxide (C 3 O 2 ) is a potential extended source of both the CO and atomic carbon emission observed in cometary comae. However, laboratory experiments on the formation and stability of C 3 O 2 in space environments have not
