(O2) rotating in the xy plane about the z axis passing through its center, perpendicular to its length. The mass of each oxygen atom is 2.66 x 10^ -26 kg, at room temperature, and the average separation distance between the two oxygen atoms is 2.02 x 10^ -10 m (atoms treated as point masses).
If the angular speed of the molecule about the z axis is 5.61 x 10^12 rad/s, what is its rotational kinetic energy in units of J?

KE=(1/2)*I*omega^2
I=m*r^2 for each atom, r being half the distance that seperates them, so in total 2*m*r^2
omega= 5.61 x 10^12 rad/s
There you go, you're all set, hope it helps!

All diatomic molecules exist in pairs when alone. It's just a rule you have to get used to. I'm pretty sure the only diatomic molecules are Nitrogen, Hydrogen, Oxygen, Bromine, Fluorine, Iodine, and Chlorine I put Carbon instead of Chlorine, My mistake :/

Type rotational kinetic energy of oxygen molecule at answers.com .I think hopefully you will get some leads not answers from which you can arrive at the answer of your question.
