Estimation of vapour pressure of organic liquids and solids



Hi everybody,
 is there a way of estimating in a crude way the vapour pressure of organic
 liquids and solids? 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?
 Best regards
