Unformatted text preview: the third, fourth, and ﬁfth excited states as well. b) Show that you do not need q , the partition function, to calculate these quantities. Show that, if you are only interested in relative populations (eg. how many more molecules are in one state compared to another state), you can always calculate this without knowing the value of q . c) I 2 is experimentally found to have vibrational energy levels at the following wavenumbers above the ground state: 213.30 cm1 , 425.39 cm1 , 636.27 cm1 , 845.93 cm1 , 1054.38 cm1 ,.. Repeat the relative population analysis you did in part (a) for the actual molecule I 2 using the experimental data. d) Compare the answers of (a) and (c) and comment. 1...
