Photodissociation of Sulfur Dioxide: The Ẽ State Revisited
The pump−probe technique has been employed to study the photodissociation processes of sulfur dioxide (SO2). The SO2 + transient has been fit to a biexponential with decay times of 230 ± 9 fs and 8 ± 4 ps. The growth of 32SO+ was determined to be 225 ± 10 fs with a decay of 373 ± 27 fs. The response...

| Zusammenfassung: | The pump−probe technique has been employed to study the photodissociation processes of sulfur dioxide (SO2). The SO2 + transient has been fit to a biexponential with decay times of 230 ± 9 fs and 8 ± 4 ps. The growth of 32SO+ was determined to be 225 ± 10 fs with a decay of 373 ± 27 fs. The response of the isotope 34SO2 + was also fit to a biexponential decay with lifetimes of 195 ± 14 fs and 4 ± 1 ps. The decay of 34SO+ was fit to 381 ± 30 fs. The results display that an inverse kinetic isotope effect is operative during dissociation of SO2 through the Ẽ state. |
