Velocity correlation function vs. x = t/τ for two values of αR (<a onClick="popup('http://www.nanoscalereslett.com/content/6/1/39/mathml/M18','MathML',630,470);return false;" target="_blank" href="http://www.nanoscalereslett.com/content/6/1/39/mathml/M18">View MathML</a>) (m = 6me, T = 300 K). Clear exponentially damped oscillations are displayed in this case.
