Abstract
The energy due to the coupling between the electronic and the nuclear motion in a molecular system has been calculated for the normal state of the hydrogen molecular ion H2+ and the lowest 1Σ and 3Σ state of the hydrogen molecule H2. It is found that this coupling is represented by a repulsive potential which is of the same order of magnitude as the van der Waals interactions at distances where the latter is important. Thus in any theoretical calculation of the interaction between light neutral atoms, it is necessary to include this coupling between the electronic and the nuclear motions.Keywords
