Nuclear spin induced isotope enrichment in CO2 photodissociation. RSP-4
Description
CO2 molecule can be dissociated by UV light to form CO and O2. Oxygen isotopic composition of these O2 and CO was first studied to discover a surprisingly large enrichment (∼100 %) of 17O during 180 nm photolysis. This was explained by nuclear spin induced perturbation causing enhanced dissociation of 17O-isotopologue during spin forbidden singlet-triplet transition in CO2 dissociation. The carbon isotope ratio in the CO product another potential candidate to see the spin effect was not analyzed. In the present work we have investigated oxygen isotope ratios in both the products and carbon isotope ratio in CO to obtain more insight in this unusual fractionation process
