Question:

At 300 K, most molecules are not in their ground rotational state. Is this also true for their vibrational degree of freedom? Calculate N_n=1 N_n=0 and N_n=2 Nn=0 for the ¹²⁷I₂ molecule. Make sure that you take the degeneracy of the levels into account for the ¹²⁷I₂ molecule for which the force constant is 172 N m⁻¹. At what temperature is N_n=2 N_n=0 = 0.500? Repeat the calculation for H₂ for which the force constant is 575 N m⁻¹ and explain the difference in the results.
