[gmx-users] Autocorrelation of dipole moment

[André Farias de Moura]

sure, the ACF for a vector gives you the average cosine between that vector
at time t=0 and the same vector at a later time lag, thus negative values may
be seen as an inversion of the direction to which the vector points
out (-1 would
be the value for a vector lying 180 degrees away from the direction at t=0).

Andre
