The rotational constant () of a linear molecule carbonyl sulfide, OCS, is 0.2 cm–1. Predict which transition in the rotational absorption spectrum will be most intense at a temperature of 298 K. (hints: OCS is considered a linear rigid rotor and the energy level with the highest population at a specific temperature can be predicted by and h = 6.626 x 10-34 J s, Boltzmann constant k = 1.38 x 10-23 J K-1 speed of light is 3.0 x 108 m s-1)
