"control of 3-atom CaOH molecule in vacuum just below 100 microkelvin, then using optical tweezer (laser) arrays separating them enabling manipulation of 1 molecule at a time into quantum ground state... image an individual molecule, which proved that a given tweezer was loaded without destruction... control each molecule's vibration, rotation, nuclear spin... imaged the molecule once again to learn more about the outcome... technique could also be used with other three-atom molecules"
