# Partition Functions

Hi All - If I have a potential energy surface with two energy states, one higher than the other, where I can make the assumption that both potential wells can be approximated via harmonic potentials with force constants kA and kB then would the partition function for the system be Z=e^(-hwA/2kT)+e^(-hwB/2kT) where wA=sqrt(kA/m) and wB=sqrt(kB/m)? Also, if the higher energy state was the more likely to be populated at some temperature T, how small would kB (the higher energy state) need to be in terms of kA?

Anyone? Maybe I should have posted this in Advanced Physics.
