What is the typical rotational frequency frot for a molecule like n2 at room temperature (25βc)? assume that d for this molecule is 1Γ₯=10β10m. take the total mass of an n2 molecule to be mn2=4.65Γ10β26kg. you will need to account for rotations around two axes (not just one) to find the correct frequency. express frot numerically in hertz, to three significant figures.
