    I'm trying to use this theory to predict Henry's constants of gases in liquids but have a couple of issues.

    When calculating Free energy of interactions the dipole moment for the inductive and dipolar contributions is often quoted in Debyes. However this value is too large yielding incorrect answers as does using units of e.s.u. cm. Using units of C cm yeilds ok answers but probably since the values are so small, I'm not convinced the answers are correct.

    Also I have to 'fudge' the answers by multiplying the RT term when calculating the entropy of solution by about 50.

    I tried the guy who wrote the papers(Robert Pierotti, 1976) but he's dead so any help from anyone would be great.

    cheers
