dc.description.abstractFourier transform infrared spectroscopy was used to record the spectra of crystalline films containing varying amounts of acetylene with either carbon dioxide or nitrous oxide. These binary films were prepared by pulsed expansion of the mixed gas onto a liquid nitrogen cooled window. The presence of new absorption bands indicate the presence of a binary phase with a concentraion independent stoichiometry. The stoichiometry for the binary phase C02-C2H2 was determined to be 1:1. Two binary phases (labelled a and B) of NsO.C2H2 were also shown to have a 1:1 stoichiometry. The binary phase C02.C2.H2 was found to be metastable with respect to its pure phases. Evidence was shown which suggests the nuclei of formation of these binary phases are cluster formed in the early stages of the supersonic expansion.
