Rotational contribution to heat capacity

  1. Nov 2, 2008 #1
    Hi all,

    I have to determine the contribution from rotational partition function. I have determined the rotational partition function as

    [tex]q_{rot} = \frac{T}{\omega}*(1+\frac{1}{3}(\frac{\omega}{T}+\frac{1}{15}(\frac{\omega}{T})^2+...)[/tex]

    where T >> omega and the expansion is Euler-Maclaurin. In order to find the internal energy I would like differentiate q with regard beta(kT) but I don't know ho to proceed... Any hints or advice appreciated thanks in advance.

    1. The problem statement, all variables and given/known data

    2. Relevant equations

    3. The attempt at a solution
