Abstract:

A method is presented for the accurate calculation of the intermolecular pair potential parameters for unlike molecules. Precise equations are derived for the force constants epsilon12 and sigma12 of a Lennard-Jones-6, delta-potential. For a repulsive exponent value delta 12 these constants are evaluated for 16 binary mixtures of different molecular structure and for all noble gas binaries. The results are compared with empirical literature-values and with values calculated from well-known combining rules. The agreement with empirical data is in some cases excellent especially for the noble gas binaries. Author
