The degrees of freedom inherent in the structure of polyatomic molecules allow for new applications spanning the fields of quantum simulation and computation, ultracold chemistry, and precision measurements of fundamental physics. For example, the complex rovibrational structure of polyatomic molecules generically gives rise to closely-spaced levels of opposite parity that result in linear Stark shifts at modest electric fields, along with states that have zero first-order electric field sensitivity. Here we present our results on laser cooling of CaOH and optical trapping of CaOH in the vibrational bending mode, which possesses such a parity doublet structure. We present microwave spectroscopy of this state for its potential use in quantum science applications. In addition, we discuss the creation of an optical tweezer array of CaOH molecules. The single particle control lent by this platform will open the door to future efforts studying interactions between molecules in optical traps.
