The gas phase reaction between 1H127l and 35Cl passes through a linear transition state, as shown in the following scheme: 1H127l+35Cl[35Cl1H127l]1H35Cl+127l The molecule 1H127I has a rotational constant B=6.511cm1, while the linear transition state has an estimated rotational constant of B=7.35102cm1. a) Explain what is meant by the rotational temperature, and calculate its values for 1H127 I and the linear transition state. Hence, comment on the validity of the analytical form of the rotational partition function for analysing this reaction at T=295K. b) Calculate the rotational partition functions for 1H127 and the linear transition state at T=295K
