Rotational and vibrational partition functions of cis-trans n-PrCHO.

Temperature (K)	Q_r^(a)	Q_v^(b)
9.38	518.5813	1.0000
18.75	1464.0056	1.0020
37.50	4137.2687	1.0486
75.00	11698.8301	1.3624
150.00	33095.6561	3.1151
225.00	60821.5883	7.6557
300.00	93661.9204	18.3964

Notes. ^(a) Q_r is the rotational contribution to the partition function. ^(b) Q_v is the vibrational contribution to the function. The total partition function of the conformer is Q_r × Q_v.
