HCl has a rotational constant of 10.59 cm−1 and a vibrational constant of 2991 cm−1.

Part A

Find the temperature, if there is one, at which the J = 0 and J = 1 rotational states have the same population.

Express your answer using two decimal places.

Part B

Find the temperature, if there is one, at which the ν = 0 and ν = 1 states have the same population.
