The recently developed variational cellular method (VCM) is used to investigate the ground and excited electronic structures of F2 and Ne2 molecules. This work reports our first attempt to apply the VCM to the study of molecular excited states. It is concluded that VCM yields potential energy curves for these molecules with a good degree of physical realism.
