Abstract
We demonstrate coherent control of the rotational and hyperfine state of ultracold, chemically stable Rb87Cs133 molecules with external microwave fields. We create a sample of ∼2000 molecules in the lowest hyperfine level of the rovibronic ground state N=0. We measure the transition frequencies to eight different hyperfine levels of the N=1 state at two magnetic fields ∼23 G apart. We determine accurate values of rotational and hyperfine coupling constants that agree well with previous calculations. We observe Rabi oscillations on each transition, allowing complete population transfer to a selected hyperfine level of N=1. Subsequent application of a second microwave pulse allows the transfer of molecules back to a different hyperfine level of N=0.
