The probability of a linear molecule being in a particular rotational level J depends on the temperature, and for J 7 0 there is a temperature Tmax at which the probability for that level reaches a maximum. Derive an expression for Tmax as a function of J and the rotational constant B, assuming that kBT W B. THINKING AHEAD [Once we have an expression for T as a function of J, how do we Find Tmax?
