摘要：

It is shown that the autocorrelation function, i.e. the scalar product < phi(0)\phi(t) > of a wave packet at times zero and t, may be calculated from the wave packet propagated until a time 1/2t. This automatically allows the computation time in the calculation of absorption spectra to be reduced by a factor of two.
