We demonstrate the coherent creation of a single NaCs molecule in its rotational, vibrational, and electronic (rovibronic) ground state in an optical tweezer. Starting with a weakly bound Feshbach molecule, we locate a two-photon transition via the |c^{3}Σ_{1},v^{'}=26⟩ excited state and drive coherent Rabi oscillations between the Feshbach state and a single hyperfine level of the NaCs rovibronic ground state |X^{1}Σ,v^{''}=0,N^{''}=0⟩ with a binding energy of D_{0}=h×147044.63(11)  GHz. We…

TLDR
This review covers recent developments in studying bimolecular chemistry at ultralow temperatures and discusses a series of studies on the reaction KRb + KRb → K2 + Rb2 initiated below 1 K, including the direct observation of a long-lived complex and a test of the statistical model using the complete quantum state distribution of the products.
Complexes formed in collisions between ultracold alkali-metal diatomic molecules and atoms
