a) The vibrational frequencies of F2, Cl2,
Br2, and I2are 917 cm-1, 525
cm-1, 325 cm-1, and 208 cm-1.
Which molecule (F2, Cl2, Br2, or
I2) has the largest number of thermally accessible
states? Make a prediction and explain your reasoning before you
perform any calculations, but assume that all molecules are exposed
to the same temperature.
b) Treat the molecular vibrations as harmonic oscillators to
calculate the vibrational partition function of the halogens and
the population of their first...
