Optically trapped polyatomic molecules are a promising platform for measurements of time-reversal symmetry violation due to their highly polarizable structure, co-magnetometer states, and long achievable coherence times [Kozyryev and Hutzler, PRL 119 (2017)]. For example, linear polyatomic molecules in the vibrational bending mode could be used to search for the electron’s electric dipole moment (eEDM), which would cause the electron to precess in the effective electric field present in polarized molecules. Here we present microwave spectroscopy of the vibrational bending mode in optically trapped CaOH molecules, and discuss progress towards electron spin resonance spectroscopy with long coherence times. Applied to heavier molecules with otherwise identical structure, these measurements would have the potential to probe physics beyond the standard model approaching PeV energy scales.
