Nielsen: Relative Tropospheric Photolysis Rates of HCHO, H13CHO, HCH18O, and DCDO Measured at the European Photoreactor Facility Page 8314. There was an error in the derivation of eq 5. The correct expression for the ratio of JA/JB is

The revised relative photolysis rates with 1σ errors are as follows:

JDCDO/JHCHO ) 0.333 ( 0.056 JDCDO/JHCH18O ) 0.401 ( 0.056 JDCDO/JH13CHO ) 0.398 ( 0.056 The following values can then be derived:

JHCH18O/JHCHO ) 0.830 ( 0.182 JH13CHO/JHCHO ) 0.837 ( 0.183 10.1021/jp068794c Published on Web 01/18/2007
