Problem 6.23. For a CO molecule, the constant € is approximately 0.00024 eV.

(This number is measured using microwave spectroscopy, that is, by measuring the

microwave frequencies needed to excite the molecules into higher rotational states.)

Calculate the rotational partition function for a CO molecule at room temperature

(300 K), first using the exact formula 6.30 and then using the approximate formula

6.31.
