CCL: calculate IR using Fourier transform of the velocity/dipole moment ACF

Hi Friends,

I want to calculate the IR of a complex from the given classical md trajectory, in xyz format.
As known this can be achieved via the Fourier transform of the velocity/dipole moment autocorrelation function.

Is there a program can do this? Any comments regarding the implement are greatly appreciated.
