Abstract
KrF excimer laser-induced reactions in the mixture of ethylene/O-2/CO2 under sub-and super-critical conditions were investigated. The main p roducts were acetaldehyde and ethylene oxide. The total quantum yield decreased with the increase of mixture density, but the branching rati o between the two products were almost independent on the density. The branching ratio was found to be what is expected if the reactive spec ies is O(P-3). Any distinctive specific pressure effect has not been o bserved in the near-critical region.
