($p, \mathrm{pd}$), ($p, \mathrm{pt}$), and ($p, p{}_{}{}^3{}_{}{}^{}\mathrm{He}$) reactions have been studied at 75 MeV on ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$ and ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$. A good energy resolution (∼400 keV) permitted the observation of several levels of the different residual nuclei. The results are analyzed with distorted-wave impulse approximation calculations and spectroscopic factors are extracted and compared with theoretical predictions. A comparison of our results with experimental data from transfer reactions on the same nuclei is made. Spectroscopic and mechanism information are discussed; in particular, the excitation of $T=1\mathrm{}$ levels in ${}_{}{}^{10}{}_{}{}^{}\mathrm{B}$ and ${}_{}{}^{14}{}_{}{}^{}\mathrm{N}$ allowed the comparison with $p-d^{*}$ ($S=0\mathrm{}$, $T=1\mathrm{}$) scattering obtained from other reactions.
