Ammonia partition function

[cheathturner]

See attached. We are attempting to reproduce the ammonia reaction equilibrium system with RASPA. We have calculated the partition functions for each element (H2, N2, NH3). However, using the same reference data (McQuarrie), we obtain slightly different results for NH3. Our calculations are attached and compared to the values provided in the RASPA documentation. Any insight or explanation for the discrepancy would be appreciated!
