The rotational constants of CH3Cl are à = 5.097 cm−1 and ì = 0.443 cm−1. Evaluate the rotational partition function explicitly (without approximation but ignoring the role of nuclear statistics) and plot its value as a function of temperature. At what temperature is the value within 5 per cent of the value calculated from the approximate formula?
