Relative tropospheric photolysis rates of acetaldehyde and formaldehyde isotopologues measured at the European photoreactor facility.
The photolysis rates of HCHO, DCDO, CH(3)CHO, and CH(3)CDO are studied by long-path FTIR spectroscopy in natural tropospheric conditions at the European Photoreactor Facility (EUPHORE) in Valencia, Spain. Average relative photolysis rates j(HCHO)/j(DCDO) = 3.15 +/- 0.08 and j(CH(3)CHO)/j(CH(3)CDO) = 1.26 +/- 0.03 are obtained from three days of experiments for each reaction in the period June 17 to July 7, 2006.
