Homework Statement
What is the typical rotational frequency frot for a molecule like N2 at room temperature (25°C)? Assume that d for this molecule is 10-10m. Take the atomic mass of N2 to be mN2=4.65x10-26kg. You will need to account for rotations around two axes (not just one) to find the correct frequency.
Homework Equations
rms angular speed: ω=sqrt{(2kT)/(md2)}
frot=ω/(2[itex]\pi[/itex])
k=1.381x10-23 J/(molecule*K)
The Attempt at a Solution
For my first attempt, I plugged the given numbers into sqrt{(3kT)/(md2)}. I used 3 instead of 2 because I was accounting for the two different axes. I'm not sure if the was the correct way to go about it. Secondly, I divided the given mass by 2. Then, I divided my answer by 2pi.
