Homework Help: Thermodynamics

Posted by chemstudent on Monday, February 23, 2009 at 2:51am.

What is the temperature of a two-level system of energy separation equivalent to 300 cm^−1 when the population of the upper state is one-half that of the lower state?

What does this "energy separation equivalent to 300 cm^−1" mean?

I can get this far:

n1 = 1/2 n0 = 1/2
e^(-E/kT) = 1/2
e^(E/kT) = 2
E/kT = ln 2
T = E / (k * ln 2)

But here, I am stuck. I don't know how to get the E value from the 300 cm^-1...
