The properties of negative-parity states in the 2.5 MeV region in ${}^{112}\mathrm{Cd}$ have been investigated with the ${(n,n}^{\prime }\gamma )$ reaction. For many of these levels, lifetimes have been measured, and $B\left(E1\mathrm{}\right)\mathrm{}$ and $B\left(E2\mathrm{}\right)\mathrm{}$ values for their decays have been determined. Several transitions exhibit enhanced $B\left(E2\mathrm{}\right)\mathrm{}$ values for decay to the $3_1^{-}$ octupole state, indicative of quadrupole-octupole coupled ${(2\mathrm{}}^{+}\otimes 3^{-})$ states. The $B\left(E1\mathrm{}\right)\mathrm{}$ values observed are typically in the range of 1–$5\times {10}^{-4}$ Weisskopf units (W.u.), irrespective of the final state.
