Abstract
Carbon dioxide isolated in argon and nitrogen matrices was reinvestigated through FTIR spectroscopy. The study of the variation of the IR absorptions with the concentration of CO 2 in the matrix, and also with the addition of different amounts of N 2 (present as an impurity in the Ar gas) was performed. Some of the bands were reassigned to the CO 2 dimer and CO 2⋯N 2 complex and some others, like the symmetric stretching mode for the CO 2 dimer and the ( ν 1 + ν 3) and (2 ν 2 + ν 3) combination bands for the CO 2 dimer and that of the CO 2⋯N 2 complex, were reported for the first time. The bonding properties of the (CO 2) 2 and CO 2⋯N 2 complexes have been interpreted by a Natural Bond Orbital (NBO) analysis in terms of “donor–acceptor” interactions.
