\text{O}_2

undergoes photochemical dissociation into one normal oxygen atom and one oxygen atom,

1.967 \text{ eV}

more energetic than normal. The dissociation of

\text{O}_2

into two normal atoms of oxygen requires

498 \text{ kJ mol}^{-1}

. What is the maximum wavelength effective for photochemical dissociation of

\text{O}_2
