1. Constructing the nuclear spin wavefunctions, how do you account for the alternation in the populations of the rotational energy levels of the ground electronic state of the H₂ molecule. For the H atom, we know I = ½.

2. Also, Using the Boltzmann expression, and including nuclear spin and orientational degeneracy, how do you calculate the relative populations of the J = 6 and J = 7 rotational states in the v(Nu)= 0 level of the ground electronic state of D₂ at 300 K. For the ground electronic state of molecular deuterium Be = 30.429 cm^-1, D = 0.011 cm^-1 and alpha = 1.049 cm^-1.

Answering question 2, I approached it by doing the following:
N(J)/N(J₀) = N(7)/N(6) = g_NS(7)/g_NS(6) = 15/13
 :delta: E = {E(J=7)} - {E(J=6)}
