Abstract
Sears's itinerant-oscillator model of liquids has been reexamined so as to be consistent with the fluctuation-dissipation theorem. An expression for the frequency spectrum of the velocity autocorrelation function is derived which is different from the one given earlier by other authors. Two cases have been considered, one corresponding to the exponential and the other corresponding to the Gaussian correlation in time of the stochastic force. Our calculated spectrum for liquid argon is in very good agreement with the machine computations of Rahman.Keywords
