Question

The umbrella of ozone in the upper atmosphere is formed from the photolysis of O_2
2
​
molecules by solar radiation according to the following reaction:

O2+hν→O+O
Calculate the cutoff wavelength above which this reaction cannot occur (in nm).

On your own, look up a plot of the solar spectrum in the upper atmosphere and identity which portion of the spectrum will cause the O2 to dissociate.

Answer 2

Answer:

Ozone photolysis is the source of the O(1D) atoms in the lower atmosphere. Here, we call the probability of the formation of an O(1D) atom in the photolysis of a single ozone molecule at a given photolysis wavelength the “O(1D) quantum yield”.
