The derived expression is a natural extension of the expression obtained by Zwanzig that assumes harmonic oscillations. The relation between the low frequency oscillation and the deviation from the harmonic behavior is also shown., http://www.hindawi.com/journals/phys/2011/645264/}, title = {The effect of the anharmonicity in a perturbation estimate of the self-diffusion coefficient}, volume = {2011}, year = {2011}, yomi = {インドウ, タカキ} }
