What it shows\: single\-photon, isotope\-selective predissociation of O3 in the Wulf band near 1 um\. The decomposition of the irradiated isotopologue is 'nearly proportional to the laser power' with 'no apparent threshold' \(Fig\. 4b\), so a one\-photon process through rotationally resolved lines of 3A2 \<\- 1A1 \(v2 = 1\-0\), not multiphoton absorption \(abstract, p\. 158\)\. Irradiating the 666 line at 10081\.30 cm^\-1 \(AL3\) decomposed about 15 % of 666 ozone in 36 h; the 668 isotopologue's own decomposition follows mostly from line overlap \(p\. 157\)\.

Why nothing is taken\: the paper gives decomposition volumes and peak\-height decays in figures only, under cell\-specific conditions \(wall decomposition, irradiation times\), with no cross section or quantum yield\. Line positions \(AL1 10074\.61, AL2 10080\.68, AL3 10081\.30, AL4 10074\.42 cm^\-1; the 666 band origin 10082\.0 cm^\-1 from Bouvier et al\. 2001\) and the isotopologue fractions are not curated quantities\. The 'absorption cross\-section \.\.\. on the order of 10^\-23 cm^2' \(p\. 156\) is an order of magnitude only \(el\_helou\_2005 measures the \(1,0\) band maximum, 3\.80 x 10^\-23 cm^2 at 294 K\)\. The statement that 3A2 lies 0\.13 eV above the dissociation limit is quoted from ab initio work \(refs\. 4, 5\: Xie et al\. 2001; grebenshchikov\_2007\)\.
