How one can calculate or find the Lennard Jones Potentials of HCl gas and chlorine gas?. Please advice. Also from where one can get the value of mean characteristic lengths of species HCl and Cl2.
Cf. Appendix B (Table), entitled “Lennard-Jones Potentials as Determined from Viscosity Data”, at: B.E. Poling , J.M. Prausnitz, J.P. O'Connell, "The Properties of Gases and Liquids", 5th ed., McGraw-Hill, 2001 (also at some earlier eds.); apud: R. A. Svehla, NASA Tech. Rep. R-132, Lewis Research Center, Cleveland, Ohio, 1962.
