I have a whole bunch of molecules and I don't need absolute values, just look for tendencies. So I imagine some calculation formula which perhaps contains temperature, possibly boiling point and melting point, or perhaps dipole moment, molecular weight etc. (easily accessible quanities). Is this wishful thinking?
