The nucleus ${}_{}{}^{18}{}_{}{}^{}\mathrm{O}$ is studied with a wave function which represents a dineutron-plus-${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$ cluster configuration. The result indicates that the dineutron clustering effect may be quite important for the structure of the three lowest states in this nucleus.
