High-spin states in ${}^{46}\mathrm{Ti}$ have been investigated with the reaction ${}^{28}\mathrm{Si}{(}^{24}\mathrm{Mg},\alpha 2p)$ at 100 MeV, using the GASP γ-ray array and the charged-particle detector ISIS. The positive parity yrast sequence has been observed up to the ${14}^{+}$ terminating state and several high-energy transitions have been established above the termination state. Both the signatures of a negative parity band have been observed up to the ${16}^{-}$ and ${17}^{-}$ terminating states, plus one more transition from an ${18}^{-}$ state at 19.086 MeV excitation. The observed states are interpreted within the frame of large scale shell model calculations in the full $\mathrm{pf}$ space (positive parity) and as particle-hole excitations from the $d_{3/2}$ shell (negative parity).
