The effects of central, spin-orbit, and tensor components of the Sussex interaction on various ground-state properties of ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$ and ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$ nuclei are studied. It is observed that a major contribution to the binding energy comes from the central part of the interaction alone. In the case of ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$, almost all of the $1p_{\frac{1}{2}}-1p_{\frac{3}{2}}$ splitting comes from the spin-orbit component. However, in ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$, the tensor part of the interaction also provides large splitting, but its contribution is of the wrong sign.
