How much energy can carbon dioxide emit?

What is the maximum energy that a carbon dioxide molecule can emit in joules per second?

That's a rather vague question or a question without a precise answer.
As an approximation we can consider such a molecule as a rigid body with 6 degrees of liberty. So $\displaystyle E=\frac{mv^2}{2}+\frac{I\omega ^2}{2}$. So it's like asking what is the maximal velocity such a molecule can have. I'm pretty sure that for high speeds the formula I gave is not valid. I might be wrong about everything though.
Otherwise I would just use $\displaystyle E=mc^2$

Thanks for your reply. I suppose I should have put the question this way: What is the maximum IR radiation that a CO2 molecule can absorb, and from that energy, what is the maximum energy it can emit?

Oh... I'm sure it deals with quantum mechanics. My knowledge is too limited for now to answer this question. So I'll let other help you on this. Clearly the question is much more precise now.
