A molecule has an excited state electronic energy level that emits radiation of 1/? = 360 cm?1 when it falls to the ground state. The ground state is non-degenerate and the excited state is doubly degenerate. Calculate:
(a) the ratio of the number of molecules in the excited state at 213 K to the
number of ground state molecules
(b) the percent of the excited molecules at 213 K.
