| contents | We investigate using optically trapped linear polyatomic molecules as probes of nuclear spin-dependent parity violation. The presence of closely spaced, opposite-parity $\ell$-doublets is a general feature of such molecules, allowing parity-violation-sensitive pairs of levels to be brought to degeneracy in magnetic fields typically 100 times smaller than in diatomics. Assuming laser cooling and trapping of polyatomics at the current state-of-the-art for diatomics, we expect to measure nuclear spin-dependent parity-violating matrix elements $iW$ with 70 times better sensitivity than the current best measurements. Our scheme should allow for 10 \% measurements of $iW$ in nuclei as light as Be or as heavy as Yb, with averaging times on order the of 10 days and 1 second, respectively. |
