我们计算了超冷（KRb）-K-40-Rb-87碱金属二聚体的微波光谱，包括超精细相互作用和存在的电场和磁场。我们表明，微波跃迁可用于转移分子之间的不同的超精细状态，但只是因为存在核四极相互作用。超精细分裂也可能使超冷分子在量子计算中的应用复杂化。在电场中取向的分子的光谱可以通过同时施加磁场而大大简化。
We calculate the microwave spectra of ultracold (KRb)-K-40-Rb-87 alkali-metal dimers, including hyperfine interactions and in the presence of electric and magnetic fields. We show that microwave transitions may be used to transfer molecules between different hyperfine states, but only because of the presence of nuclear quadrupole interactions. Hyperfine splittings may also complicate the use of ultracold molecules for quantum computing. The spectrum of molecules oriented in electric fields may be simplified dramatically by applying a simultaneous magnetic field.
