✦ Synopsis

In this work it is shown that because of the different symmetry of the variables the time dependence of the autocorrelation function of the time derivative of the anisotropic polarizability density can be different from that of the molecular angular momentum density autocorrehtion fun&m.

Thus the information on this angular momentum correlation function that can be deduced from that of the time derivative of the anisotropic polarizability density can be limited.
