VUV irradiation of carbon dioxide (CO2) and ammonia (NH3) complexes in argon matrix

In this study, we characterized by FTIR spectroscopy the 1:1 and 2:1 molecular complexes between NH3 and CO2 in argon matrix at low temperature. In addition we tentatively identified the 1:2 molecular complex. The structures of the complexes were established from B3LYP calculations. Moreover, we showed that the VUV irradiation of the 1:1 complex forms the NH2OH:CO complex.
