Hello all,
I have some trouble understanding the partition function. In wikipedia it is written that the partition function needs to be calculated with the multiplicity of the states:
z=SUM[g(E)exp(-BE)]
where g(E) is the multiplicity of the states corresponding to energy E.
It is also well known that the relative probability of two different states with different energy is P(E1)/P(E2) = exp(-BE1)/exp(-BE2).
According to the partition function which is the sum of all probabilities, the expression above should be g(E1)exp(-BE1)/g(E2)exp(-BE2)
What is true... ?
Thank you for helping.
