Self- and distinct velocity correlation functions and related diffusion coefficients have been calculated. Special attention has been paid to the dynamic cross correlations which have been computed through recently introduced relative mean molecular velocity correlation functions which are independent on the reference frame. The differences between the distinct velocity correlations and diffusion coefficients in different reference frames (mass-fixed, number-fixed, and solvent-fixed) are discussed.9 p.application/pdfeng(c) American Physical Society, 1994Cristal·lografiaPropietats de la matèriaCrystallographyProperties of matterinfo:eu-repo/semantics/article87871info:eu-repo/semantics/openAccess
