We present a procedure which allows the extension of linear-response calculations to open-shell nuclei. Using simple and intermediate coupling shell model wave functions for the ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$ ground state we apply our procedure to calculate the characteristics of multipole giant resonances. Our results agree well with experiment and are compatible with the predictions of other open-shell random phase approximation models.
