Partition function data

Main Question or Discussion Point

Hi,
Where would I find data for rotational/vibrational temperatures for a particular molecule (ethane)? I tried googling but had no luck. Also can you compute the moments of inerta for a particular (simple) molecule?

Statistical Mechanics by McQuarrie p.132 table 8-1 has the values for $CH_4$ and several other molecules. (Looking at it more closely=$CH_4$=methane. No, ethane $C_2H_6$ is not in that table). $\\$ Edit: I did find this in a google: https://cccbdb.nist.gov/exp2x.asp?casno=74840&charge=0 Perhaps it will be helpful.
