In this article the $1^1 \Sigma^+$ electronic ground state is studied up to near the dissociation limit. Calculations have been carried out using previous experimental data and taking into account the exchange energy that cannot be neglected. In this calculations, new values for the multipolar van der Waals coefficients Cn have been obtained showing a good agreement with the previous theoretical ones.
