STRUCTURE OF MOLECULAR-COMPLEXES IN LIQUID CO2 SOLUTIONS OF WATER

wThe calculated anharmonic frequencies and intensities of simultaneous vibrational transitions in CO2-H2O and (CO2)(2)-H2O hydrogen-bonded c omplexes are compared with known experimental data. Hydrogen-bonded co mplexes form in liquid CO2 solutions of water under normal conditions, unlike the gas phase in which the CO2 and H2O molecules are coupled b y van der Waals bonds. The majority of these complexes are 2:1 complex es.
