What is that T?

Cold, interstellar, molecular clouds have been seen to contain the cynogen molecule, CN, whose first rotational excited states have an energy of 4.7*10^-4 eV above the ground state. There are actually 3 such excited states, all with the same energy. In 1941, studies of these molecular clouds, using the absorption of starlight passing through them, showed that for every ten CN molecules that are in the ground state, a total of approximately three others are in the three excited states (this means that, on average, one is in each of these 3 excited states). To account for this data, astronomers postulated that the molecules were in thermal equilibrium with some reservoir at a well defined temp... click for more
