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:
(integral is from 0 to infinity)
Zrot = integrla of (2j + 1)e-j(j + 1)epsilon/kT dj = kT/epsilon.
