A computational scheme to study the dynamics of many-electrons in molecular systems by wavepackets method is presented. Several approaches to calculation of nonlinear optical properties for molecules under time-independent or time-dependent external electronic fields are presented. Some simple examples of one-dimensional two- or three-electron systems are demonstrated concretely. Implications of these results are discussed in relation to the validity of the many electron wavepackets (MEWP) method.
