ABSTRACT
The photochemical fixation of carbon dioxide has stimulated considerable interest, in providing models of prebiotic photosynthesis J Earlier work on such artificial photosynthesis has been reviewed.^

The direct photolysis of CO2 in the homogeneous gas phase occurs only by excitation in the vacuum UV region, at \ = 120 to 167 nm. The reaction steps involved have been represented by
CO2 + hv CO + 0 ( ‘D)
