### Calculate the rotational partition function for CO molecule

For a CO molecule, the constant epsilon is approximately 0.00024 eV. Calculate the rotational partition function for a CO molecule at room temperature (300 K), first using the exact formula: (j = 0 to ∞) Zrot = sum of (2j + 1)e-E(j)/kT = sum of (2j + 1)e-j(j + 1)epsilon/kT, and then using the approximate formula: (
