We perform two sets of calculations at basis F using the point charge nuclear model and the finite nuclei modelled by Gaussian charge distribution to see the effect nuclear model on the calculated properties. From Table , we see that the magnitude of the calculated properties is either slightly changed or hardly affected except the S-PS interaction constant due to the use of the point charge nuclei over the finite nuclei for the moderately heavy molecular system SrF. The S-PS electronic structure constant is found to be zero with the point charge nuclear model, as expected, because of the presence of nuclear charge density ρ N (r) in the matrix element of the S-PS interaction parameter (see Eq. 14).
