Ultracold polyatomic molecules have potentially wide-ranging applications in quantum simulation and computation, particle physics, and quantum chemistry. For atoms and small molecules, direct laser cooling has proven to be a powerful tool for quantum

Quantum-mechanical methods of solving the polyatomic vibrational Schrodinger equation need higher quality zero-order approximations than ones originating from the harmonic oscillator (HO). ...

We explore the feasibility of optically forming long-range tetratomic and larger polyatomic molecules in their ground electronic state from ultracold pairs of polar molecules aligned by external fields. Depending on the relative orientation of the in

We study optical cycling in the polar free radical calcium monohydroxide (CaOH) and establish an experimental path towards scattering $\ensuremath{\sim}{10}^{4}$ photons. We report rovibronic branching ratio measurements with precision at the $\ensur

The vibrational spectroscopy of the semirigid (i.e., without large-amplitude motions) polyatomic molecule is reviewed. The normal modes are defined. The importance of molecular symmetry is pointed out. The Coriolis interaction and the anharmonic reso

The rotational spectroscopy of the polyatomic molecule is reviewed. The determination of the rotational constants for the different types of rotors is discussed. The rovibrational correction and the electronic correction to the rotational constants a

A way how a general rovibronic Hamiltonian for a polyatomic molecule can be obtained using generalized coordinates and introducing a “well” for the potential function of nuclear oscillations has been shown. Eigenfunctions for individual types of

We investigate the creation of stable heteronuclear polyatomic molecules based on the three-body and higher order Efimov state via a generalized stimulated Raman adiabatic passage scheme. Within the mean-field approximation, we establish the multi-pa

Mobilities of polyatomic molecule ions in helium gas were measured at 85 K and room temperature using a low-temperature drift tube. They differed from the typical behavior shown by atomic or small molecular ions in helium owing to the influence of at
